・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.

·在广岛大学150MeV电子环装置上建立了激光-康普顿散射实验系统，该实验系统由选举束监测器、激光光学器件和光子计数器组成。试验分别于1999年7月和2000年2月进行。构建并测试了激光功率积累腔的原型。它达到了大约1500的功率累积系数。安装电子环腔的真空室已准备好，并将于2000年安装。·观察非线性康普顿散射的实验已经在大阪大学激光工程研究所进行。在此基础上，完成了对线性区域康普顿散射的测试实验。非线性康普顿实验预计在2000财政年度进行。·对在光子-光子对撞机中探测顶夸克的可行性进行了模拟研究。我们发现，使用光子-光子对撞机，我们预计每年可以产生大约1000个事件。研究结果分别在1999年5月西班牙LCWS99和1999年12月美国e-e研讨会上发表。
