Radio Frequency Quadrupole and Alternating Phase Focusing Methods Used in Proton Linear Accelerator Technology in the USSR

摘要

The RFQ system has been especially effective in providing the practical means of approaching the space propagation criteria of high current level, low injection energy, adequate reliability, efficiency, and moderate size. Another method of simultaneous acceleration and focusing of ions under Soviet development has been the alternating phase focusing (APF) system, which has recently achieved a successful feasibility proof.
