摘　　要：在模拟计算程序LINE-ACC/PC基础上,结合单一搜索方法和非线性最小二乘算法编程,实现一个X波段2 MeV行波加速管的物理设计。应用此方法可以有效缩短加速管的优化设计时间。文章给出的优化计算可应用于一类常相速周期结构的加速管设计。文章同时给出了纵向粒子动力学、盘荷波导的几何尺寸及加速管的工作特性等方面的计算结果。A computer program is rewritten based on LINE-ACC/PC and combined simplex searching method and nonlinear least-squares algorithms in order to accomplish physical design of an X-band 2 MeV traveling wave（TW） electron linac accelerator tube. The time of designing accelerator tube can effectively be shortened. The optimization displayed in the paper can be applied to design of accelerator tubes with constantphase velocity period structure. Calculations of longitudinal particle dynamics, structure parameters and working character also are carried out and demonstrated.
