An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
The Z machine has also conducted experiments with arrays of tungsten wires rather than liners. The space inside the wire array was filled with polystyrene, which helps homogenize the X-ray flux. By removing the polystyrene core, Sandia was able to obtain a thin 1.5 mm plasma cord in which 10 million amperes flowed with 90 megabars of pressure.
The use of megavoltage x-rays for treatment first became widespread with the use of Cobalt-60 machines in the 1950s. [9] However prior to this other devices had been capable of producing megavoltage radiation, including the 1930s Van de Graaff generator and betatron. [10] [11] [12]
Van de Graaff generators are still used as accelerators to generate energetic particle and X-ray beams for nuclear research and nuclear medicine. [2] The voltage produced by an open-air Van de Graaff machine is limited by arcing and corona discharge to about 5 MV. Most modern industrial machines are enclosed in a pressurized tank of insulating ...
The device was originally built in the 1970s for high-power x-ray research, was later re-directed to studies for the Strategic Defense Initiative (SDI), and is now being used for magnetized target fusion research. Shiva Star was named after the Hindu god Shiva, partly because its prototype originally had four "arms"; it later got six "arms
X-RIS (for X-Ray Imaging Solutions) is a Belgian company based in Liège and active in the field of digital radiography in non-destructive testing and in security. Founded in 2010, the company won the Belgium Deloitte Technology Fast 50 in 2015 and again in 2017. It has supplied x-ray solutions to Airbus, Safran, TOTAL, the TÜV.
