Efficient Sources of Soft X-Ray Radiation Based on Fast Capillary Discharges

9401952 Rocca对于现有和新兴应用的相干和非相干X射线辐射的紧凑和高效源的开发有着重大的兴趣。 我们以前的研究已经研究了产生高度电离的等离子体柱= 200微米直径的电子温度的几百电子伏特和良好的稳定性，利用电流是1至2个数量级低于那些通常用于创建热等离子体在大型脉冲功率发生器。 建立在这些最近的结果，其中包括从3 p-3s的激光候选人在40 kA放电中的钙类钙的跃迁发射的观察，我们建议推进在快速毛细管放电等离子体中的软X射线放大的搜索。 拟议的研究还包括研究电存储能量到非相干X射线的转换效率，以探索开发高效非相干X射线源的可行性。 ***

9401952 Rocca There is significant interest in the development of compact and efficient sources of coherent and incoherent x-ray radiation for existing and emerging applications. Our previous research has studied the generation of highly ionized plasma columns of =200um diameter with electron temperatures of a few hundred eV and good stability utilizing currents that are 1 to 2 order of magnitude lower than those commonly used to create hot plasmas in large pulsed power generators. Building on these recent results, which include the observation of emission from the 3p-3s laser candidate transitions in neon-like Ca in a 40kA discharge, we propose to advance on the search for soft x-ray amplification in the plasma of fast capillary discharges. The proposed research also includes the study of the conversion efficiency of the electrical stored energy into incoherent x-rays to explore the feasibility of developing an efficient incoherent x-ray source. ***
