Embodiment Construction

[0030] Below in conjunction with accompanying drawing and specific embodiment the content of the present invention is described in further detail:

[0031] The invention proposes a design method of the transverse bremsstrahlung reflective triode, which converts the pulse power from coaxial transmission to plate transmission, and loads it on the reflective triode to realize electron lateral emission. The transverse reflective triode not only solves the problem of inconsistency in space potential between cathode and anode, but also makes full use of the radiation fields on both sides of the anode to improve the efficiency of electronic power.

[0032] Such as figure 1 and Figure 6 As shown, a bremsstrahlung reflective triode includes a reflective triode cavity 1, an anode base 2, an anode 3, a cathode 4, a transverse cover plate 5, a forward cover plate 6, an insulating plate fixing nut 7, and an insulating plate transition piece 8 and an insulating plate 10; the insulating p...

Abstract

The invention relates to a bremsstrahlung reflection triode for generating strong pulse hard X rays. The problems that the gap potentials of two cathodes and anodes of an existing bremsstrahlung reflection triode are inconsistent, and a radiation field cannot be fully utilized are solved. The triode comprises a reflection triode cavity, an anode base, an anode, cathodes, transverse cover plates, aforward cover plate, an insulation plate fixing nut, an insulation plate transition piece and an insulation plate. The part, connected with the insulation plate, of the reflection triode cavity is acylinder, the part, away from the insulation plate, of the reflection triode cavity is transited into a closed cavity, and two parallel flat plates are arranged on the opposite surfaces of the closedcavity; the two cathodes are respectively arranged on the two flat plates of the closed cavity; the anode is positioned between the two cathodes; the anode is arranged on the anode base, the anode base is installed on a water line inner cylinder through the insulation plate transition piece, and the insulation plate transition piece is fixed through the insulation plate fixing nut. The transversecover plates are arranged on the two flat plates of the closed cavity respectively, and the forward cover plate is arranged at the axial tail end of the closed cavity.

Description

technical field [0001] The invention relates to the technical field of pulse power, in particular to a bremsstrahlung reflective triode for generating strong pulse hard X-rays. Background technique [0002] Intense pulsed hard X-ray sources are widely used in experimental studies of various radiation effects. In traditional single-gap diodes, the high-current pulsed electron beam emitted by the cathode bombards a target with a high atomic number to generate bremsstrahlung. Since the electromagnetic pulse effect of the system requires pulsed hard X-rays with an energy spectrum of 10-100keV, the maximum energy of the pulsed electron beam used for targeting must be less than 300keV, which requires the terminal voltage of the single-gap diode to be lower than 300kV. In a single-gap bremsstrahlung diode, the high-current pulsed electron beam emitted by the cathode only interacts with the anode conversion target once, so it is difficult to fully utilize the energy of the electron...
