摘要
介绍了神光-Ⅲ主机装置能源系统的功能要求、组成结构和设计方法,以及关键单元器件的功能要求和设计方法。该系统是片状放大器系统的重要组成部分,由6个束组共108套最大储能为1.2 MJ的能源模块组成,总储能达到110 MJ(最大130 MJ)。每套模块产生一个脉宽610 μs(10 %峰值)的电流脉冲,驱动10组、共20支氙灯,为片状放大器提供泵浦能量,峰值电流为0.25 MA。目前投入试运行的36套能源模块的各项电气性能指标满足设计要求,能确保片状放大器小信号增益系数达到5.0%/cm,为片状放大器提供足够的泵浦能量,满足激光器的能量需求。
Abstract
As an important component of segment amplifier system,SG-Ⅲ laser facility’s power conditioning system (PCS) consists of 108 power conditioning modules (PCMs),which are divided into six segments.With the maximum energy stored in each PCM reaches 1.2 MJ,PCS stores 110 MJ energy,and 130 MJ maximally.Each PCM produces a pulse current for driving ten groups of Xenon flshlamps,20 flshlamps in total,and provides pumping energy for segment amplifier system.The current pulsewidth is 610μs,and the peak value is 0.25 MA.PCMs’ function requirements,compositions and structure,and design methods are introduced, as well as function requirements and design methods of the key components.Performance of the first 36 PCMs applied to SG-Ⅲ laser facility proves that the specifications of PCS meet the design requirements and can make sure the small signal gain coefficient of segment amplifier reach 5.0% per centimeter, and PCS can provide adequate pumping energy for amplifier and fit the bill of lasers.
