FIELD: physics.SUBSTANCE: acceleration tube relates to X-ray equipment and can be used in a pulsed X-ray accelerator to obtain short, high-intensity X-ray flashes for detecting high-speed processes in optically dense media. The acceleration tube includes an acceleration tube insulator 1, an insulator container 2 and a sealed insulating housing 3 of the diode assembly of the acceleration tube with a radiation exit window, inside of which there is a vacuum which separates a cathode and an anode which is in form of a steel pipe 4. The cathode 5 is in form of a concentric ring with end-to-end grooves 8 between radial electrode projections 7, the number of which is less than three (a forced current distribution cathode). The anode is an anode rod 4 in form of a cone-shaped holder made of iron, with a spherical head 6 in form of a sphere made of tungsten.EFFECT: high uniformity of spatial distribution of radiation and stability of operation of the acceleration tube.3 cl, 4 dwg |
