摘　　要：用MAFIA程序计算了电子回旋加速器加速腔上加速孔、阴极孔、辅助孔 (第Ⅱ加速型 )对加速场分布的影响。计算结果表明 :进行粒子动力学模拟计算时 ,忽略这种影响是合理的。另用对电子加速到最终能量跟踪计算的方法 ,同时以能散度为依据 ,计算电子稳定加速的参数范围 ,并给出S波段电子回旋加速器工作参数的计算结果。计算用C语言编制的程序在微机上进行。The influence on the accelerating electromagnetic field caused by the accelerating apertures, cathode hole and supplementary aperture(the second acceleration type), is studied by using the MAFIA program. The calculation indicates that ignoring this influence is reasonable for simulating the electron motion. A C language program is compiled for the simulation, which follows the electron track of the whole motion and take the energy spread as criterion of the stable acceleration, so as to determine the range of parameters of microtron. A group of detailed result of S band microtron is also given.
