摘要:
利用形成线并联的方法产生高压三脉冲,需要在形成线和加速腔负载间串联硅堆隔离网络,以隔离不同形成线间的相互影响,并将不同形成线先后产生的高压脉冲汇流成三脉冲串传输到加速腔.硅堆放置于封闭的油箱中,箱体结构的设计将直接影响汇流后三脉冲的波形品质和硅堆的使用寿命.通过对高压硅堆内部电势分布的模拟分析和实验验证,明确了影响硅堆使用寿命的主要原因;设计实验测量了汇流结构各部分对汇流脉冲前沿的影响程度,综合分析汇流结构对硅堆使用寿命的影响,明确了汇流结构的优化方向,并在此基础上确定了神龙二号三脉冲直线感应加速器硅堆汇流结构的最终设计.
Abstract:
Touches off the parallel connected pulse forming lines one by one,use silicon diodes to isolates the high voltage pulses,several single square pulses can be combined to form a MHz repetition rate multi-pulses string.The structure of the con-fluence box,which the silicon diodes are putted into,affects the life-time of diodes and the pulses'risetime of accelerate voltage clearly.This paper describes the simulations and high-voltage experiments to study the correlation between the confluent structure and the pulses confluent effect,and introduces the final confluent system of the three-pulses LIA"Dragon II".
