A platform SWE-2 used for single wire explosion experiments has been designed, established, and commissioned. This paper describes the design and initial experiments of SWE-2. In summary, two pulsed current sources based on pulse capacitors and spark gaps are adopted to drive sub-microsecond and microsecond time scale wire explosions in a gaseous/liquid medium, respectively. In the initial experiments, a single copper wire was exploded in air, helium, and argon with a 0.1-0.3 MPa ambient pressure as well as tap water with a 283-323 K temperature, 184-11 000 μS/cm conductivity, or 0.1-0.9 MPa hydrostatic pressure. In addition, the diagnostic system is introduced in detail. Energy deposition, optical emission, and shock wave characteristics are briefly discussed based on experimental results. The platform was demonstrated to operate successfully with a single wire load. These results provide the potential for further applications of this platform, such as plasma-matter interactions, shock wave effects, and reservoir simulations.
已设计、建立并调试了一个用于单丝爆炸实验的SWE-2平台。本文描述了SWE-2的设计和初步实验。简而言之，采用了两个基于脉冲电容器和火花隙的脉冲电流源，分别在气态/液态介质中驱动亚微秒和微秒时间尺度的丝材爆炸。在初步实验中，一根铜丝在空气、氦气和氩气中爆炸，环境压力为0.1-0.3MPa，以及在温度为283-323K、电导率为184-11000μS/cm或静水压力为0.1-0.9MPa的自来水中爆炸。此外，还详细介绍了诊断系统。基于实验结果，对能量沉积、光发射和冲击波特性进行了简要讨论。该平台已被证明在单丝负载下能成功运行。这些结果为该平台的进一步应用提供了潜力，如等离子体-物质相互作用、冲击波效应和储层模拟。
