Abstract

The possibility of designing a compact source of soft X-ray radiation without the accompanying generation of fast electrons is under study. The source is formed by the interaction of high-contrast femtosecond laser pulses of relativistic intensity with supersonic argon gas jets. The optimal conditions are found under which the conversion coefficient to soft X-ray radiation in the range of 2.9–3.3 keV reaches 8.57 × 10^–5.

相对论强度高飞秒激光脉冲作用下在超音速氩气射流中形成的软X射线辐射源

摘要

正在研究设计紧凑的软X射线辐射源而不产生快速电子的可能性。源是由相对论强度的高对比度飞秒激光脉冲与超音速氩气射流相互作用形成的。找到了最佳条件，在此条件下，在2.9–3.3 keV范围内，软X射线辐射的转换系数达到8.57×10 ^–5。
