LINEAR ION ACCELERATOR Russian patent published in 1999 - IPC

FIELD: design of new and reconstruction of operating linear accelerators. SUBSTANCE: linear ion accelerator has vacuum enclosure , accelerating structure, HF power supply system with high-frequency power input. High-voltage source of injection voltage has high-voltage ion injector which body is grounded. High-voltage input of injection voltage is connected to point of accelerating structure that has minimal high-frequency voltage. Input is manufactured in the form of non-uniform coaxial line whose parameters are defined by certain expressions. Length of thin part of input equals relation of length of operational wave of resonator to four. Decimal logarithm from relation of screen diameter to diameter of thin part of input is greater or equal to decimal logarithm from relation of screen diameter to diameter of thick part of input. Excitation loop of high-frequency fields is isolated from accelerating structure. EFFECT: decreased leakage of high-frequency power from resonator through input, enhanced operational reliability of accelerator. 1 dwg
