项目摘要

The research has been concentrated on the highly sophisticated generation system of the soft X-ray with the energy range of 200-500 eV through the inverse Compton scattering between high quality electron beam and highly stabilized Nd : YLF laser light. High quality electron beam has been obtained from laser photocathode RF gun with specially designed for this project. On the other hand, highly stabilized Nd :YLF laser system is used for the generation of electron beam ( by 4^<th> harmonics of ND : YLF fundamenta1)and collision (by fundamental of Nd :YLF) experiments. The quality of electron beam has been measured by double slit scan technique for relatively low energy electron beam. The emittance of the electron beam is achieved to 3mm mrad, which is one of the lowest records for RF accelerated electron. The stability of laser light against to the local oscillator has been achieved to 0.26 ps. The energy of laser light per pulse has been obtained around 30mJ. The development of collision chamber is also successfully carried out. As the results, very precise measurements of soft X-ray with very low level noise have been realized. By using the system, the electron beam size measurements at the collision point and the dependence of collision angel for generated X-ray photons are demonstrated. The X-ray focusing system with specially designed zone plate is also developed.

这项研究集中在软X射线的高度复杂的生成系统上，其能量范围为200-500 eV，通过高质量电子束和高度稳定的ND：YLF激光光之间的逆向康普顿散射。高质量的电子梁是从激光光电电极RF枪获得了专门为该项目设计的。另一方面，高度稳定的ND：YLF激光系统用于电子束的产生（由ND：YLF Fundamenta1的4^<th>谐波）和碰撞（通过ND：YLF的基本实验）实验。电子束的质量已经通过双缝扫描技术来测量相对较低的能量电子束。电子束的发射率达到了3mm mrad，这是RF加速电子的最低记录之一。激光光对局部振荡器的稳定性已达到0.26 PS。每脉冲的激光能量已得到30mj的大约30mJ。碰撞室的发展也已成功进行。由于结果，已经实现了非常精确的X射线测量值。通过使用系统，证明了碰撞点处的电子光束尺寸测量值以及对产生的X射线光子的碰撞天使的依赖性。还开发了具有特殊设计的区域板的X射线聚焦系统。
