TUNGSTEN DISK XRAY GENERATOR
TUNGSTEN DISK XRAY TRIAL

It was actually an accidental discovery by a German Mechanical Engineer Wilhelm Conrad Roentgen in 1895. However, unlike visible light, they have higher energy and shorter wavelength. Like Visible light, X-Rays are also part of the electromagnetic spectrum. This post will discuss in detail about what is X-Ray Radiography, types of imaging using X-Ray, how it works, applications, advantages and Disadvantages.

(1982) Photon mass attenuation and energyabsorption coefficients from 1 keV to 20 MV. The repetition rate was less than 50 Hz, and the effective focal spot size was equivalent to the anode diameter. The pulse width ranged from 40 to 100 ns, and the X-ray intensity was less than 1в™± ОјC kg в€’1 at 0в™µ m per pulse. Thus the maximum photon energy could be easily controlled by varying the A-C space, and the tube current roughly increased according to increases in the charged voltage. The peak tube voltage was primarily determined by the anode-cathode (A-C) space, and the peak tube current was less than 0в™µ kA. The flash X-ray tube of the demountable-diode type and was composed of a rodshaped anode tip made of tungsten, a disk cathode made of graphite and a tube body made of polymethylmethacrylate. The total capacity during the main discharge was 425 pF, and the maximum output voltage from the pulser was about 1в™№ times the charged voltage. The two condensers in the pulser were charged from 40 to 60 kV, and the electric charges were discharged to the X-ray tube repetitively to generate flash X-rays. The high-voltage pulser employed a modified two-stage surge-Marx circuit. Fundamental studies of a repetitive flash X-ray generator using a diskcathode radiation tube are described.
