High-efficient HF-energy input into an accelerating resonator

The problem of enchancing the efficiency of the energy transfer into a superconducting accelerating resonator up to approximately 100% at any possible degrees of energy take-off by particle bunches and at alternating unequal time intervals between adjacent bunch passage is solved. It is proposed to use an additional superconducting resonator placed before the accelerating resonator and having direct coupling with the latter. The resonators are tuned to the same frequency. The dependence of the efficiency of energy transfer into the superconducting accelerating resonator with 3x109 proper Q-factor is given for the case when an electron bunch and a positron bunch pass through the resonator at times separated by 1.5x10-6 s and 6.2x10-6 s intervals, and the degree of energy take-off by the electron bunch and positron bunch defined as a ratio of energy difference of the fundamental oscillation mode before and after bunch passage and energy before particle bunch passage through the resonator is different and equal to 0.82 and 0.76, respectively
