This paper describes an X-pinch device recently developed at Seoul National University (SNU). The SNU X-pinch device is designed and fabricated to accommodate various diagnostics as well as conduct versatile experiments. It is easy to change the capacitance of the pulse generator because the capacitor bank has a modular design without insulation oil or gas. This allows us to perform a variety of experiments with a wide capacitance range from 80 to 800 nF. The operating voltage of the SNU X-pinch device is controlled from 20 to 100 kV by adjusting the gas pressure inside a triggered spark-gap switch. Triggering of the spark-gap switch is synchronized with the operation of a pulsed laser to diagnose the X-pinch plasma at the proper time. A large vacuum chamber precisely machined from an aluminum mono-block is attached to the top of the pulse generator. It is designed to accommodate not only various X-pinch loads but also various diagnostic apparatus such as optical components. Initial experiments with the SNU X-pinch device have successfully generated x rays with wires of various materials and sizes. The device will be used not only to explore the dynamics of X-pinch plasmas but also as a test stand for diagnostics of high-energy-density plasmas.

用于首尔国立大学多功能 X-pinch 实验的模块化 X-pinch 设备

本文介绍了首尔国立大学 (SNU) 最近开发的 X-pinch 设备。SNU X-pinch 装置的设计和制造可以适应各种诊断以及进行多功能实验。由于电容器组采用模块化设计，无需绝缘油或气，因此很容易改变脉冲发生器的电容。这使我们能够以 80 到 800 nF 的宽电容范围进行各种实验。SNU X-pinch 装置的工作电压通过调节触发式火花隙开关内的气压控制在 20 到 100 kV 之间。火花隙开关的触发与脉冲激光的操作同步，以在适当的时间诊断 X 收缩等离子体。一个由铝制单体精密加工而成的大型真空室连接到脉冲发生器的顶部。它的设计不仅可以适应各种 X-pinch 负载，还可以适应各种诊断设备，例如光学部件。SNU X-pinch 装置的初步实验已经成功地用各种材料和尺寸的电线产生了 X 射线。该设备不仅将用于探索 X-pinch 等离子体的动力学，还将用作诊断高能量密度等离子体的试验台。
