摘　　要：在漂移管直线加速器(DTL)中束流的聚焦问题是通过漂移管中嵌入四极透镜来解决,如果采用常规的直流激励磁铁会引起漂移管的热变形。本文介绍了采用脉冲方波激励源的电路拓扑结构可行性方案,通过计算机的仿真模拟,并进行了电源样机的制作,其测试结果与理论分析一致,验证了该方案的可行性。In drift tube linac （DTL）, the particle focusing problem is provided by the drift tube embedded with quadruple magnet （Q）. If the quadruple magnet is excited by DC power supply, it would result in thermodynamics distortion of the drift tube. A feasible scheme for the rectangle pulse power excitation is described in this paper. The simulation and the experimental studies on the power supply model prove the feasibility.
