摘要
双层喷气负载作为减小瑞利-泰勒不稳定性的重要手段,在Z箍缩实验中得到广泛应用。本文主要阐述双层喷气负载的机械设计,包括整体结构以及密封、同步等。分析了影响内外气室气密性的主要因素及弹簧参数的选取。对由线圈、铁芯及拉杆组成的拉阀系统进行了验算。结果表明,在所选参数下,系统完全满足实验要求。最终在"强光一号"加速器上进行了结构验证性实验,获得了满意的效果。
The double shell gas puff is applied extensively in Z pinch experiments because it can reduce R-T instability during the implosion phase. The design of the double shell gas puff was described, including the whole configuration, the synchronization of the gas release valves and the airproof of the inner and the outer chambers. The main factors which affect the airproof of the chambers were analyzed and the parameters of the springs were calculated. The gas release system consisting of the winding, iron core and the pull rod was also simulated, and the result proved that the system completely satisfied the demand of the Z pinch experiments. At last, the result of the testing experiment on ＇Qiangguang I＇ is given and it proves the practicality of the double shell gas puff.
