X-RAY Tube With Photocathode
Description
X-ray tube with cold cathode (PRT) uses built-in photomultiplier tube (PMT), as a source of electrons, instead of traditional cathodes. X-rays are adjusted by light hit the PMT photocathode. Light-emitting diode, lamp or any other source can be used as the light source. PRT can be applied in medicine (X-ray tomography), biology, x-ray space communications, in equipment for X-ray structure and X-ray spectral analyses.
X-RAY Tube With Photocathode
Features
Operation in continuous and pulse modes;
In pulse mode provides 100% modulation in range from 100 Hz to 1 MHz with a du-ty cycle of 2 (the fill factor of 0.5);
Zero lag;
X-ray intensity is adjusted by light-emitting diode current;
Purity of spectrum due to photocathode (cold cathode), as a source of electrons;
Variation of PMT photocathode material allows control of the light of different range from UV to near-IR;
Provides anode current up to 1 mA at low anode voltages (is important with Be window);
The same device could be used to produce soft X-ray (at low voltages) and X-ray of medium hardness (at voltages up to 100 kV).
