FIELD: roentgen diagnostics and therapy in medicine and various processes including flaw detection and scientific research. ^ SUBSTANCE: proposed X-ray pulse generator has X-ray tube effective surface area of whose point cathode and anode is not over 10-6 m2 and preset cathode-to-anode distance is minimum, 10-3 m; it also has high-voltage pulse generator whose heavy-current high-voltage pulse shaper is made in the form of heavy-current high-voltage vacuum or gas-discharge switching unit incorporating electrode that controls switching unit triggering and is provided with additional high-voltage filter inserted in its circuit. Linear size of X-ray radiator focal spot is 0.1-0.5 mm. X-ray quanta energy can be regulated between 20 and 150 keV; X-ray pulse length is about 10-8 to 10-6 s. ^ EFFECT: reduced size of X-ray tube. ^ 1 cl, 1 dwg |
