Generation of photon beams by the laser-Compton scattering

实验系统，对电子束监视器、激光光学和光子计数器的支持，用于广岛大学150 MeV电子环设施的激光康普顿散射。该测试于1999年7月和2000年2月进行。一个关于激光功率建造洞穴的原型是经过构造和测试的。它实现了大约1，500个发电厂的发电能力。真空室将安装在电子环上的洞穴已准备好，并将在2000财政年度安装。The Experiment for the Observation of the nonlinear Compton scattering has been performed at the Institute of Laser Engineering in Osaka University。该安装已经完成，并进行了测试实验，以观察线性区域的组件散射是成功的。2000财政年度的非线性康普顿实验是预期的。一项模拟研究，用于在一个光子-光子对撞机中进行顶部夸克探测的可行性。这是我们发现的，我们可以期待在一年内与光子碰撞的1，000个活动。报告了两个国际讲习班的结果，LCWS 99西班牙，1999年5月和美国电子讲习班，1999年12月。

・The experimental system, consisting of the election beam monitor, laser optics and the photon counter, for the laser-Compton scattering was constructed at the 150MeV electron ring facility at Hiroshima university. The test experiment was performed in July 1999 and February 2000.・A prototype of the laser power build-up cavity was constructed and tested. It achieved the power build-up factor of about 1,500. The vacuum chamber to install the cavity into the electron ring was prepared and will be installed FY2000.・The experiment for the observation of the nonlinear Compton scattering has been performed at the Institute of Laser Engineering in Osaka University. The setup has been completed and the test experiment to observe the Compton scattering in linear region was successful. The nonlinear Compton experiment is expected in FY 2000.・A simulation study for the feasibility of top quark detection in a photon-photon collider was performed. It was found that we can expect about 1,000 event in a year with the photon-photon collider. The results was reported in two international workshop, LCWS99 Spain, May 1999 and e-e- workshop USA, December 1999.
