摘要
用Lie代数方法分析了相对论脉冲束在静电加速管中的传输 ,得到其三级近似轨迹。根据需要还可以扩展到更高级近似。在分析中 ,把加速管看成由入口膜片、均匀场加速区和出口膜片三个单元组成 ;为了便于描述粒子在加速管中的轨迹 ,把加速管也分成若干段 ,在每个小区间上施加Lie变换。
The Lie algebraic analyses for the pulsed beam transport in the electrostatic accelerating tubes were presented. The solutions through third order were obtained and could be extended to higher order if desired. In the analysis, the accelerating tube was divided into three elements: entrance aperture lens, uniform accelerating field and exit aperture lens. To obtain analytical forms of aberrations, the uniform accelerating region was also divided in several small segments, in which the Lie map was performed.
