项目摘要

The productions of the high temperature and high density plasmas with 10^<20>/cm^3 and several key become possible by the development of pulsed power technology, because the extremely high power over 100GW can be supplied into the plasma. The applications of high energy density plasmas cover the wide fields such as soft x-ray and neutron sources, x-ray lasers, charged particle beam sources, accelerators and et al. .The conventional pulsed power generators, which consist of the Marx bank and the water capacitor have been used as the electric source for the production of high energy density plasma. However, since these pulsed power generators are large, heavy and expensive, it was very difficult to mount and maintain-except the institutes. Therefore, the number of researchers is limited.The aim of this research is to show that the light-weight and compact pulsed power generator using the inductive energy storage can be used to produce the high energy density plasma. The gas-puff 2-pinch plasma is used as the load of the pulsed power generator. The inductive energy storage pulsed power generator, ASO-II, which was developed at Kumamoto university, is used here. The soft x-ray from the high energy density plasma is compared between the cases with and without the opening switches. The ASO-II with the opening switch produces the current with faster rise time than ASO-II without it. The intensity of soft x-ray from the high energy density plasma was larger in the case using the current with the faster rise time, even though the current was smaller at the tine when the soft x-ray was produced. Therefore, the inductive energy storage pulsed power generator is effective to produce the high energy density plasmas.

高温和高密度等离子体具有10^<20>/cm^3的生产，并且由于脉冲功率技术的发展而变得可能是可能的，因为可以将超过100GW的极高功率提供到等离子体中。高能密度等离子体的应用覆盖了宽阔的田间，例如软X射线和中子源，X射线激光器，带电的粒子梁源，加速器等。。传统的脉冲发电机由马克思银行和水电容器组成，已用作生产高能量密度等离子体的电源。但是，由于这些脉冲发电机很大，沉重且昂贵，因此很难安装和维护研究机构。因此，研究人员的数量受到限制。这项研究的目的是表明，使用电感储能的轻质和紧凑的脉冲发电机可用于产生高能量密度等离子体。燃气2杆血浆用作脉冲发电机的负载。在这里使用了在库曼托大学开发的电感储能脉冲发电机ASO-II。在带有开口开关和没有开关的情况下，比较了来自高能密度等离子体的软X射线。带有开关开关的ASO-II比没有它的ASO-II产生的电流更快。在这种情况下，使用具有更快的上升时间的电流，从高能密度血浆中的软X射线强度较大，即使产生软X射线时的电流在Tine处较小。因此，电感储能脉冲发电机可有效产生高能密度等离子体。
