摘要

从光束能量100-200 MeV、共振频率350 MHz的二维电磁分析出发，对分离漂移管直线加速器加速单元进行了优化设计。为了找到最大有效分流阻抗（ZTT）和最小基尔帕特里克数的最佳电池设计，将电池参数分为三组：槽直径、面角和漂移管直径以及机头参数。发现ZTT和基尔帕特里克数存在特征趋势，并从电路参数和电池内电磁场变化的角度定性解释了特征趋势。基于这些特点，讨论了SDTL单元优化的系统过程。

Accelerating cell design optimization for separated drift tube linac in KOMAC

Optimization on accelerating cell for separated drift tube linac (SDTL) is conducted from 2D electromagnetic analysis in the beam energy range of 100–200 MeV and resonance frequency of 350 MHz. To find the optimum cell design for maximized effective shunt impedance (ZTT) and minimized Kilpatrick number, cell parameters are swept by classifying parameters in to three groups: tank diameter, face angle and drift tube diameter, and nose parameters. It is found that there exists characteristic trend on ZTT and Kilpatrick number which is qualitatively interpreted in the view of variation of circuit parameters and electromagnetic field in the cell. Based on those characteristics, systematic process on optimizing SDTL cell is discussed.
