用于束流输运计算的TRANSPORT-EM程序

TRANSPORT-EM——A PROGRAM USED FOR CALCULATING BEAM LINE

摘要: <正> 一、TRANSPORT程序的功能及其局限性 TRANSPORT程序是一个采用一、二阶传输矩阵和束矩阵计算粒子运动轨迹和束包络的计算程序。所计算的系统包括漂移空间、两极磁铁、四极磁铁、六极磁铁、螺线管、行波加速段等。该程序能够处理束心位移、元件不准直和绕光轴旋转公差等问题。并且,能够自动进行系统优化设计,自动调整元件的参数以满足对系统在聚焦成象和象差修正方面的要求。

Abstract: TRANSPORT--EM is a modified version of TRANSPORT, which has somenew functions such as calculating electrostatic elements and plotting beam profi-les. It becomes more complete and suitable for optimization design of chargedparticle optics systems, especially ion implanters and electrostatic accelerators.
