19. X-Ray Tube Beam Blanking Using a Retarding Potential
The setup with the RTW x-ray tube shown in Picture 37 has been modified using an auxiliary board to allow for blanking of the x-ray pulse. For initial testing the 1S2 rectifier tube pair in the upper right is an excellent simulation of the RTW filament. Once optimized, the results were exceptional. It can be see that the current blanks from 0 to 200 uA with excellent speed and precision.
