They also changed the font on their jersey tops and shortened the name on the home whites to read simply "Rays" while keeping "Tampa Bay" on the road grays.

In , the home uniforms were again tweaked to include still more green. The primary home whites became a sleeveless jersey worn with green sleeved undershirts, and the primary home caps were changed from black to green.

In addition, a small ray with a long tail was added under the name "Rays" on the chest of the home jerseys. The Rays staged a "Turn Back the Clock" promotion with a retro theme and throwback uniforms several times early in their existence, and it has become an annual tradition since On these special occasions, Rays have worn the uniforms of the Tampa Tarpons of the Florida State League in , , and , the St.

The Rays have worn their own uniforms for Turn Back the Clock night only once: For Turn Back the Clock night during the , , and seasons, the Rays took the field wearing specially designed Tampa Bay Rays "faux-back" uniforms that represented what the team might have worn had the franchise existed during the late s and early 80s.

For example, the Houston Astros wore their s "Rainbow Guts" uniforms, the New York Mets wore the road uniforms of their championship team, [38] the Chicago White Sox wore their red and white home uniforms from the s, and the Baltimore Orioles wore their rare all-orange uniforms from the early s.

Pete Saints uniforms from the early s, and the Los Angeles Dodgers wore the gray road uniforms of the World Series-winning Brooklyn Dodgers to honor Don Zimmer , who played on that Dodger team and was a senior adviser for the Rays prior to his death.

Rays management also gave away a bobblehead at the game featuring a young Zimmer in a Dodgers uniform and an older Zimmer in a Devil Rays uniform.

Rich Herrera served as the host during pre- and post-game shows for the Tampa Rays Baseball Radio Network from — Slowes went to the Washington Nationals , where he is now lead announcer, while Olden pursued a photography career before replacing Bob Sheppard as the public address announcer at Yankee Stadium in In , the Rays became the second team to enter into a contract to have games broadcast nationally by Compass Media Networks in a Game of the Week format.

The broadcast team utilized during the season was TJ Rives calling play-by-play and a rotating circuit of analysts in Rob Dibble , Jeff Nelson , and Steve Phillips.

However, after the season, Fox Sports signed an agreement to become the exclusive local broadcaster of the Rays, and will air games per year through Most Rays home games are now broadcast in HD.

Magrane departed after conclusion of the season to take a position at the MLB Network. Bobbleheads This year the Rays released several bobbleheads.

On April 24 the Rays released the famous "Joe Gnome" bobblehead. May 24—26 saw the release of the Fernando Rodney bobblehead in his famous shooting-the-arrow position.

On July 6 the team released the Evan Longoria retro bobblehead. Bobbleheads The first bobblehead released was Kyle Farnsworth on May June 3 saw the release of a Desmond Jennings Bobblehead.

Coach Joe Maddon saw his bobblehead released on June On June 29 the Rays released the whimsical Zim Bear. Although this was not a bobblehead, the likeness of long-time coach Don Zimmer proved to be a fan favorite.

The last bobblehead was Matt Joyce on September It is based on the true story of pitcher Jim Morris , who had a brief but famous Major League Baseball career with the team.

He was persuaded to try out for professional ballclubs and signed with the Tampa Bay Devil Rays organization. Jim Morris spent parts of two seasons with the Tampa Bay Devil Rays as a reliever, pitching 15 innings in 21 games, with an earned run average of 4.

Although widespread support has been slow to build with the lack of success in its first ten seasons, it has taken some cues from the powerhouses of the American League East.

Whereas Red Sox fans are referred to as Red Sox Nation , the Orioles fan base is referred to Birdland, and Yankee fans are referred to as Yankees Universe and the team itself being called the " Evil Empire " , the Rays have adopted the term Rays Republic for their fan base.

The team has also had its fair share of notable fans and outrageous fan traditions over the years. Since then, it has become a standard feature of home games, something akin to the Sacramento Kings of the NBA and the bells their fans ring during games.

Road teams have often considered the cowbell a nuisance. Once a year the Rays hold an annual "cowbell night" and give away free cowbells. Cowbells are available for purchase throughout the year as well.

The cowbells are rung most prominently when the opposing batter has two strikes, when the opposing fans try to chant, and when the Rays make a good play.

A large anthropomorphic cat, wearing a Rays jersey, appears on the screen wielding a turntable similar to those used by rap DJs.

Loud music is played over the PA system while the arrival of the DJ Kitty is proclaimed on display boards throughout the ballpark.

The character was created in by Rays entertainment director Lou Costanza in an attempt to rally the Rays players and the fans at Tropicana Field.

Rays games are frequently visited by professional wrestlers , as there are a large number of wrestlers living in the Tampa Bay Area.

John Cena appears on occasion. The Rays held a "Legends of Wrestling Night" on May 18, , featuring several wrestling matches after the game, an 8—4 loss to the Florida Marlins.

Outfielder and wrestling fan Jonny Gomes ran interference for the Nasty Boys during the main event. Gomes participated again, this time making a post-match save for the Nasty Boys.

During the playoffs, Rays players and coaches sport mohawk haircuts. The trend started during their World Series run. The phrase was originally created by manager Joe Maddon while riding his bike after the season.

The meaning of the phrase was that if nine players play nine innings of hard baseball everyday, that team would become one of the eight teams who qualify for the post-season.

Prior to season, the Rays had never had a winning season in franchise history, much less a post-season appearance. After a slow start to the season, the Rays began to pick up speed and found themselves among the best teams in the league that year.

His idea to put the slogan on the back of the shirt, rather than the front, was that a person who was walking behind someone wearing the shirt would see it.

The Rays played well enough throughout the year that they surpassed their previous team record for wins in a single season by more than 30 wins and ultimately clinched a spot in the MLB post-season for their first postseason appearance in franchise history.

With each level the Rays reached, the equation was changed. In the end, they did not win the World Series , losing to the Philadelphia Phillies four games to one.

He wanted the players to understand that "in order to build this new road we have to be better than we were last year. Though they finished the season in 3rd place with an 84—78 record, making it the second best season in franchise history, they failed to reach the post-season.

For the season , another slogan was created. Unlike the previous two seasons, this slogan did not involve any sort of math. Historically, the team had a habit of stranding runners on third base with less than two outs.

In practices during the season, the Rays would run the "get-the-man-in drill" to improve situational hitting. The Tampa Bay Rays have retired three numbers.

He wore but a single article of clothing or adornment, a small collar of gold from which depended upon his chest a great ornament as large as a dinner plate set solid with huge diamonds, except for the exact center which was occupied by a strange stone, an inch in diameter, that scintillated nine different and distinct rays ; the seven colors of our earthly prism and two beautiful rays which, to me, were new and nameless.

Muffled in the full morning light, the invisible sun was only known by the spread intensity of his place; where his bayonet rays moved on in stacks.

Half way up the steep was a yawning cave, black as night beyond the point where the rainbow rays of the colored suns reached into it.

Because we should have seen our continents and seas in a new light-- the first resplendent under the solar rays , the latter cloudy as represented on some maps of the world.

They were tears of pity, young lady, that heaven blesses and instead of falling from my eyes like the everyday tears that we all of us shed, they turned into two rays of light which slanted nearer and nearer to the man standing at the altar with you, till they touched his breast.

The two, with half a dozen thin-legged children, lived in a tumble-down frame house beside a creek at the back end of the Wills farm where Ray was employed.

We hated this, because Sara Ray was always so maddeningly self-conscious of having an escort. The Heat- Ray had shaved the chimney tops and passed.

It arrived but was not used. While the shooting itself had not been lethal, gangrene had developed along the path of the bullet, and McKinley died of septic shock due to bacterial infection six days later.

A child who had been shot in the head was brought to the Vanderbilt laboratory in Before trying to find the bullet an experiment was attempted, for which Dudley "with his characteristic devotion to science" [30] [31] [32] volunteered.

The tube was fastened at the other side at a distance of one-half inch from the hair. In August Dr. Hawks, a graduate of Columbia College, suffered severe hand and chest burns from an x-ray demonstration.

It was reported in Electrical Review and led to many other reports of problems associated with x-rays being sent in to the publication.

Morton , and Nikola Tesla also reported burns. Elihu Thomson deliberately exposed a finger to an x-ray tube over a period of time and suffered pain, swelling, and blistering.

The many applications of X-rays immediately generated enormous interest. Workshops began making specialized versions of Crookes tubes for generating X-rays and these first-generation cold cathode or Crookes X-ray tubes were used until about Crookes tubes were unreliable.

They had to contain a small quantity of gas invariably air as a current will not flow in such a tube if they are fully evacuated.

However, as time passed, the X-rays caused the glass to absorb the gas, causing the tube to generate "harder" X-rays until it soon stopped operating.

Larger and more frequently used tubes were provided with devices for restoring the air, known as "softeners". These often took the form of a small side tube which contained a small piece of mica , a mineral that traps relatively large quantities of air within its structure.

However, the mica had a limited life, and the restoration process was difficult to control. In , John Ambrose Fleming invented the thermionic diode , the first kind of vacuum tube.

This used a hot cathode that caused an electric current to flow in a vacuum. This idea was quickly applied to X-ray tubes, and hence heated-cathode X-ray tubes, called "Coolidge tubes", completely replaced the troublesome cold cathode tubes by about In about , the physicist Charles Barkla discovered that X-rays could be scattered by gases, and that each element had a characteristic X-ray spectrum.

He won the Nobel Prize in Physics for this discovery. The Coolidge X-ray tube was invented during the following year by William D.

It made possible the continuous emissions of X-rays. X-ray tubes similar to this are still in use in The use of X-rays for medical purposes which developed into the field of radiation therapy was pioneered by Major John Hall-Edwards in Birmingham, England.

Then in , he had to have his left arm amputated because of the spread of X-ray dermatitis on his arm. The cars would allow for rapid X-ray imaging of wounded soldiers so battlefield surgeons could quickly and more accurately operate.

From the s through to the s, x-ray machines were developed to assist in the fitting of shoes and were sold to commercial shoe stores.

The X-ray microscope was developed during the s. The Chandra X-ray Observatory , launched on July 23, , has been allowing the exploration of the very violent processes in the universe which produce X-rays.

Unlike visible light, which gives a relatively stable view of the universe, the X-ray universe is unstable. It features stars being torn apart by black holes , galactic collisions, and novae, and neutron stars that build up layers of plasma that then explode into space.

For technical and political reasons, the overall project including the X-ray laser was de-funded though was later revived by the second Bush Administration as National Missile Defense using different technologies.

Phase-contrast X-ray imaging refers to a variety of techniques that use phase information of a coherent x-ray beam to image soft tissues.

It has become an important method for visualizing cellular and histological structures in a wide range of biological and medical studies.

There are several technologies being used for x-ray phase-contrast imaging, all utilizing different principles to convert phase variations in the x-rays emerging from an object into intensity variations.

A disadvantage is that these methods require more sophisticated equipment, such as synchrotron or microfocus x-ray sources, X-ray optics , and high resolution x-ray detectors.

X-rays with high photon energies above 5—10 keV, below 0. The term X-ray is metonymically used to refer to a radiographic image produced using this method, in addition to the method itself.

Since the wavelengths of hard X-rays are similar to the size of atoms, they are also useful for determining crystal structures by X-ray crystallography.

There is no consensus for a definition distinguishing between X-rays and gamma rays. One common practice is to distinguish between the two types of radiation based on their source: X-rays are emitted by electrons , while gamma rays are emitted by the atomic nucleus.

Some measurement techniques do not distinguish between detected wavelengths. However, these two definitions often coincide since the electromagnetic radiation emitted by X-ray tubes generally has a longer wavelength and lower photon energy than the radiation emitted by radioactive nuclei.

Thus, gamma-rays generated for medical and industrial uses, for example radiotherapy , in the ranges of 6—20 MeV , can in this context also be referred to as X-rays.

X-ray photons carry enough energy to ionize atoms and disrupt molecular bonds. This makes it a type of ionizing radiation , and therefore harmful to living tissue.

A very high radiation dose over a short period of time causes radiation sickness , while lower doses can give an increased risk of radiation-induced cancer.

In medical imaging this increased cancer risk is generally greatly outweighed by the benefits of the examination.

The ionizing capability of X-rays can be utilized in cancer treatment to kill malignant cells using radiation therapy.

It is also used for material characterization using X-ray spectroscopy. Hard X-rays can traverse relatively thick objects without being much absorbed or scattered.

For this reason, X-rays are widely used to image the inside of visually opaque objects. The most often seen applications are in medical radiography and airport security scanners, but similar techniques are also important in industry e.

The penetration depth varies with several orders of magnitude over the X-ray spectrum. This allows the photon energy to be adjusted for the application so as to give sufficient transmission through the object and at the same time provide good contrast in the image.

X-rays have much shorter wavelengths than visible light, which makes it possible to probe structures much smaller than can be seen using a normal microscope.

This property is used in X-ray microscopy to acquire high resolution images, and also in X-ray crystallography to determine the positions of atoms in crystals.

X-rays interact with matter in three main ways, through photoabsorption , Compton scattering , and Rayleigh scattering. The strength of these interactions depends on the energy of the X-rays and the elemental composition of the material, but not much on chemical properties, since the X-ray photon energy is much higher than chemical binding energies.

Photoabsorption or photoelectric absorption is the dominant interaction mechanism in the soft X-ray regime and for the lower hard X-ray energies.

At higher energies, Compton scattering dominates. However, the general trend of high absorption coefficients and thus short penetration depths for low photon energies and high atomic numbers is very strong.

For soft tissue, photoabsorption dominates up to about 26 keV photon energy where Compton scattering takes over.

For higher atomic number substances this limit is higher. A photoabsorbed photon transfers all its energy to the electron with which it interacts, thus ionizing the atom to which the electron was bound and producing a photoelectron that is likely to ionize more atoms in its path.

An outer electron will fill the vacant electron position and produce either a characteristic x-ray or an Auger electron.

These effects can be used for elemental detection through X-ray spectroscopy or Auger electron spectroscopy. Compton scattering is the predominant interaction between X-rays and soft tissue in medical imaging.

Part of the energy of the photon is transferred to the scattering electron, thereby ionizing the atom and increasing the wavelength of the X-ray.

The scattered photon can go in any direction, but a direction similar to the original direction is more likely, especially for high-energy X-rays.

The probability for different scattering angles are described by the Klein—Nishina formula. The transferred energy can be directly obtained from the scattering angle from the conservation of energy and momentum.

Rayleigh scattering is the dominant elastic scattering mechanism in the X-ray regime. Whenever charged particles electrons or ions of sufficient energy hit a material, X-rays are produced.

X-rays can be generated by an X-ray tube , a vacuum tube that uses a high voltage to accelerate the electrons released by a hot cathode to a high velocity.

The high velocity electrons collide with a metal target, the anode , creating the X-rays. In crystallography, a copper target is most common, with cobalt often being used when fluorescence from iron content in the sample might otherwise present a problem.

When the electrons hit the target, X-rays are created by two different atomic processes:. So the resulting output of a tube consists of a continuous bremsstrahlung spectrum falling off to zero at the tube voltage, plus several spikes at the characteristic lines.

The voltages used in diagnostic X-ray tubes range from roughly 20 kV to kV and thus the highest energies of the X-ray photons range from roughly 20 keV to keV.

Both of these X-ray production processes are inefficient, with only about one percent of the electrical energy used by the tube converted into X-rays, and thus most of the electric power consumed by the tube is released as waste heat.

When producing a usable flux of X-rays, the X-ray tube must be designed to dissipate the excess heat. A specialized source of X-rays which is becoming widely used in research is synchrotron radiation , which is generated by particle accelerators.

Its unique features are X-ray outputs many orders of magnitude greater than those of X-ray tubes, wide X-ray spectra, excellent collimation , and linear polarization.

Short nanosecond bursts of X-rays peaking at keV in energy may be reliably produced by peeling pressure-sensitive adhesive tape from its backing in a moderate vacuum.

This is likely to be the result of recombination of electrical charges produced by triboelectric charging. The intensity of X-ray triboluminescence is sufficient for it to be used as a source for X-ray imaging.

X-rays can also be produced by fast protons or other positive ions. The proton-induced X-ray emission or particle-induced X-ray emission is widely used as an analytical procedure.

X-rays are also produced in lightning accompanying terrestrial gamma-ray flashes. The underlying mechanism is the acceleration of electrons in lightning related electric fields and the subsequent production of photons through Bremsstrahlung.

X-ray detectors vary in shape and function depending on their purpose. Imaging detectors such as those used for radiography were originally based on photographic plates and later photographic film , but are now mostly replaced by various digital detector types such as image plates and flat panel detectors.

For radiation protection direct exposure hazard is often evaluated using ionization chambers , while dosimeters are used to measure the radiation dose a person has been exposed to.

The first use of X-rays under clinical conditions was by John Hall-Edwards in Birmingham , England on 11 January , when he radiographed a needle stuck in the hand of an associate.

On February 14, Hall-Edwards was also the first to use X-rays in a surgical operation. On February 5, live imaging devices were developed by both Italian scientist Enrico Salvioni his "cryptoscope" and Professor McGie of Princeton University his "Skiascope" , both using barium platinocyanide.

In May he developed the first mass-produced live imaging device, his "Vitascope", later called the fluoroscope , which became the standard for medical X-ray examinations.

Dally had a habit of testing X-ray tubes on his hands, and acquired a cancer in them so tenacious that both arms were amputated in a futile attempt to save his life and in he became the first known death attributed to X-ray exposure.

President William McKinley was shot twice in an assassination attempt. While one bullet only grazed his sternum , another had lodged somewhere deep inside his abdomen and could not be found.

A worried McKinley aide sent word to inventor Thomas Edison to rush an X-ray machine to Buffalo to find the stray bullet.

It arrived but was not used. While the shooting itself had not been lethal, gangrene had developed along the path of the bullet, and McKinley died of septic shock due to bacterial infection six days later.

The penetration depth varies with several orders of magnitude over the X-ray spectrum. This allows the photon energy to be adjusted for the application so as to give sufficient transmission through the object and at the same time provide good contrast in the image.

X-rays have much shorter wavelengths than visible light, which makes it possible to probe structures much smaller than can be seen using a normal microscope.

This property is used in X-ray microscopy to acquire high resolution images, and also in X-ray crystallography to determine the positions of atoms in crystals.

X-rays interact with matter in three main ways, through photoabsorption , Compton scattering , and Rayleigh scattering.

The strength of these interactions depends on the energy of the X-rays and the elemental composition of the material, but not much on chemical properties, since the X-ray photon energy is much higher than chemical binding energies.

Photoabsorption or photoelectric absorption is the dominant interaction mechanism in the soft X-ray regime and for the lower hard X-ray energies.

At higher energies, Compton scattering dominates. However, the general trend of high absorption coefficients and thus short penetration depths for low photon energies and high atomic numbers is very strong.

For soft tissue, photoabsorption dominates up to about 26 keV photon energy where Compton scattering takes over. For higher atomic number substances this limit is higher.

A photoabsorbed photon transfers all its energy to the electron with which it interacts, thus ionizing the atom to which the electron was bound and producing a photoelectron that is likely to ionize more atoms in its path.

An outer electron will fill the vacant electron position and produce either a characteristic x-ray or an Auger electron. These effects can be used for elemental detection through X-ray spectroscopy or Auger electron spectroscopy.

Compton scattering is the predominant interaction between X-rays and soft tissue in medical imaging. Part of the energy of the photon is transferred to the scattering electron, thereby ionizing the atom and increasing the wavelength of the X-ray.

The scattered photon can go in any direction, but a direction similar to the original direction is more likely, especially for high-energy X-rays.

The probability for different scattering angles are described by the Klein—Nishina formula. The transferred energy can be directly obtained from the scattering angle from the conservation of energy and momentum.

Rayleigh scattering is the dominant elastic scattering mechanism in the X-ray regime. Whenever charged particles electrons or ions of sufficient energy hit a material, X-rays are produced.

X-rays can be generated by an X-ray tube , a vacuum tube that uses a high voltage to accelerate the electrons released by a hot cathode to a high velocity.

The high velocity electrons collide with a metal target, the anode , creating the X-rays. In crystallography, a copper target is most common, with cobalt often being used when fluorescence from iron content in the sample might otherwise present a problem.

When the electrons hit the target, X-rays are created by two different atomic processes:. So the resulting output of a tube consists of a continuous bremsstrahlung spectrum falling off to zero at the tube voltage, plus several spikes at the characteristic lines.

The voltages used in diagnostic X-ray tubes range from roughly 20 kV to kV and thus the highest energies of the X-ray photons range from roughly 20 keV to keV.

Both of these X-ray production processes are inefficient, with only about one percent of the electrical energy used by the tube converted into X-rays, and thus most of the electric power consumed by the tube is released as waste heat.

When producing a usable flux of X-rays, the X-ray tube must be designed to dissipate the excess heat. A specialized source of X-rays which is becoming widely used in research is synchrotron radiation , which is generated by particle accelerators.

Its unique features are X-ray outputs many orders of magnitude greater than those of X-ray tubes, wide X-ray spectra, excellent collimation , and linear polarization.

Short nanosecond bursts of X-rays peaking at keV in energy may be reliably produced by peeling pressure-sensitive adhesive tape from its backing in a moderate vacuum.
