摘要
为了对即将建成的PTS装置的实验能力进行分析, 对装置的工作模式及波形调节能力进行了分析。装置具有三种工作模式:短脉冲模式、长脉冲模式和波形调节模式。在不同的工作模式下, 装置可以进行不同负载的实验研究。在基本工作模式下, 在15 nH负载上输出前沿90 ns、幅值8~10 MA脉冲电流。通过电路模拟, 对装置在三种工作模式下预计的负载电流输出进行了分析, 短脉冲模式下装置负载电流的上升时间约90 ns, 长脉冲模式时约200 ns, 波形调节模式时可以达到400 ns。模拟结果表明, 通过调节激光触发气体开关的触发方式和脉冲输出开关及装置其他参数, PTS装置可以输出脉冲前沿100~400 ns、波形形状在一定范围可调的强电流脉冲。
Abstract
A high power pulse device called primary test stand (PTS) is under-developed at the Institute of Fluid Physics, CAEP. PTS contains 24 modules with identical components that the design parameters of the device are 8 MA to 10 MA current, the frontal rising time of current 90 ns. Because laser triggered gas switches on PTS can be independently triggered by 12 lasers, and by shorting out the water switches, it is possible to operate PTS in three different modes. They are: a short-pulse high current mode, a long-pulse high current mode, and a tailored wave shape long pulse mode for isentropic compression experiments (ICE).The predict currents are estimated by a full-circuit model of PTS. These predict currents about 10 MA for a same equivalent inductance load in three different modes. In the short-pulse mode PTS will be able to provide currents up to 10 MA with a rise time of 100 ns. In the long-pulse mode PTS will be able to provide currents up to 10 MA with a rise time of 200 ns. Tailored wave shape output will also be possible on PTS, with a rise time up to 400 ns. The Tailored wave shape long pulse mode is studied by the settings of triggered manners of laser triggered gas switches and operation models of water switches.
