METHOD OF CONTROL OF ENERGY OF CHARGED PARTICLES IN LINEAR RESONANCE ACCELERATOR Russian patent published in 1994 - IPC

FIELD: acceleration equipment. SUBSTANCE: method relates to control of energy in linear resonance accelerator having n drift tubes and is accomplished by excitation of deflecting field in one intermediate k-th drift tube to provide for extraction of particles from acceleration zone. At same time working frequency of accelerating field is measured in range f_o-f_o± Δf/n and number k of drift tube is chosen in compliance with expression K=n(W_k/W_n), where n=1, 2 ...k ..., W_k is required energy of extracted particles, eV, W_n is final energy of particles at output of resonator. Such operating condition makes it possible to split wide range of energy retuning W_o-W_o± ΔW± into comparatively small intervals W_o-W_o ± ΔW/n with preservation of autogeneration mode. EFFECT: expanded range of control over energy of accelerated particles. 2 dwg
