Optimization of quasiperiodic structures in a linear resonance ion accelerator

A method is proposed for optimizing the parameters of a linear ion accelerator with rectangular or trapezoidal shape of the accelerating voltage between the tubes, systematic allowance being made for the quasiperiodicity of their arrangement. Numerical calculations have demonstrated the effectiveness of the method and also the fairly simple structure of its realization. A detailed algorithm is given. An estimate is made of the interval of entrance phases, the maximal value of which exceeds by several percent the limits previously predicted.Translated from Izvestiya Vysshikh Uchebnykh" Zavedenii, Fizika, No. 6, pp. 81–85, June, 1980.
