三脉冲功率系统模块

采用基于并联Blumlein脉冲形成线的MHz重复频率脉冲功率技术和基于激光触发气体开关的多级触发系统，设计了脉冲功率系统模块，该模块具备6路输出能力，每路均可以MHz重复频率猝发方式输出三脉冲，幅度可达300 kV。对模块中的Blumlein装置、脉冲汇流、隔离网络、触发系统等部件参数进行了设计。以多脉冲直线感应加速器感应腔作为负载，对该模块的性能进行了分析，结果表明:模块中每个脉冲的输出时间抖动小于2.3 ns（标准差），脉冲间最小时间间隔大于500 ns时可在负载上获得高品质波形。

Module for three-pulsed power system

A module is designed for six-channel, three-pulsed power system, which is based on MHz repeating rate burst high-voltage generator with Blumlein pulse forming lines connected in parallel and multi-stage laser trigger system. Parameter designs of Blumlein device, confluent/blocking network, and trigger system are discussed. The analysis and simulation results show that the module meets the needs of multi-pulse linear induction accelerator. The output voltage with an amplitude of 300 kV, time jitter less than 2.3 ns （standard deviation）, and repetition rate of MHz level is achieved.
