The compact, high-intensity-, and highly-stable- Compton scattering X-ray source using the X-band linac and Nd:YAG laser has been developed at the Nuclear Professional School, the University of Tokyo. In this dissertation, the experimental verification of the 3.5-cell X-band thermionic cathode RF gun was mainly studied. In the chapter 3, we calculated and evaluated the properties of the X-rays generated via Compton scattering. The angular distribution, spectrum, and intensity of the X-rays were calculated. The maximum X-ray energy is 43.8 keV and its total intensity is about 1.0 x 109 photons/s with the electron beam energy of 30 MeV and laser intensity and its wavelength of 1.4 J and 532 nm. The stability of the X-ray yields was evaluated to be less than 10 %. The beam optimization and its stability were discussed. In addition, the construction of the beam line and waveguide system for X-band linac and its high-power experiments were carried out. Furthermore, the laser system for the … More Compton scattering experiment was constructed and its performances were evaluated. Here, the important results and new knowledge throughout these studies are summarized as follows.1 The high-power experiments on the 3.5-cell X-band thermionic cathode RF gun were performed and the 2 MeV electron beam was measured. This experimental verification of high-energy (-2 MeV) multi-bunch electron beam generation from the X-band thermionic cathode RF gun is achieved first in the world.2 The construction of the whole RF system including the X-band thermionic cathode RF gun and X-band accelerating structure were carried out. RF feeding of 40 MW to the accelerating structure and 5.5 MW to the RF gun were achieved. In addition, We summarized the experiences and deduced the guideline of the high-powered RF conditioning. These knowledges will be important roles to realize X-band compact high-energy accelerators from now on.3 The laser pulse circulation system for the Compton scattering experiment was constructed and its properties were evaluated. Focusing of the laser at 150 (horizontal) and 300 (vertical) micro m at rms was established. Then, its positioning stability within micro m was also confirmed. Furthermore, the experimental setup for the Compton scattering are constructed. This setup includes the beam diagnostic section. We developed some beam diagnostic schemes that can measure the four-dimensional beam parameters at the collision point. Less

东京大学原子能专业学校研制了一种紧凑型、高强度、高稳定性的康普顿散射X射线源，它采用X波段直线加速器和Nd：YAG激光器。本文主要对3.5室X波段电子枪的实验验证进行了研究。在第三章中，我们计算和评价了康普顿散射产生的X射线的性质。计算了X射线的角分布、光谱和强度。当电子束能量为30 MeV，激光强度为1.4 J，波长为532 nm时，X射线的最大能量为43.8 keV，总强度约为1.0 × 109光子/秒。X射线产率的稳定性被评估为小于10%。讨论了光束的优化及其稳定性。此外，还进行了X波段直线加速器束线和波导系统的搭建及其高功率实验。此外，激光系统用于 ...更多信息 构建了康普顿散射实验，并对其性能进行了评价。在此，本文将这些研究的重要成果和新认识总结如下：1.对3.5室X波段电子枪进行了高功率实验，测量了2 MeV电子束流。该实验在国际上首次实现了X波段电子枪产生高能（~ 2 MeV）多束团电子束的实验验证。2.完成了包括X波段电子枪和X波段加速结构在内的整个射频系统的搭建。实现了向加速结构的40 MW的RF馈送和向RF枪的5.5 MW的RF馈送。此外，我们总结了经验，推导出高功率射频调理的指导方针。这些知识对今后实现X波段紧凑型高能加速器具有重要的指导意义。3.构建了用于康普顿散射实验的激光脉冲循环系统，并对其性能进行了评价。激光聚焦在150（水平）和300（垂直）微米的rms。同时，也验证了其在微米级的定位稳定性。在此基础上，建立了康普顿散射的实验装置。此设置包括射束诊断部分。我们发展了一些束流诊断方案，可以测量碰撞点处的四维束流参数。少
