Quark Nuclear Physics with a Photon Beam

由于 2010 财年末发生的东日本地震造成了不可估量的损失，我们尚未实现该项目的目标。这是该项目的最新进展报告。我们构建了一个大型探测器系统 FOREST，并开发了一种新颖的目标系统和快速数据采集系统来实现我们的目标。到目前为止，我们获得了一个优秀的数据集，在 的阈值区域具有精细的能量步长。摄影制作以及单张的基本数据。生产。下一代 4. EM 热量计 BGOegg 已完成，移至 SPring-8，并开始运行。

We have not achieved our aims in this project because of immeasurable damage suffered from the East Japan Earthquake that took place at the end of FY2010. This is a progress report on the project up to date. We constructed a large detector system, FOREST, and developed a novel target system and a fast data-acquisition system to reach our goals. We obtained so far an excellent data set with a fine energy step in the threshold region of . photoproduction as well as the basic data for single . production. A next generation 4. EM calorimeter, BGOegg, was completed, moved to SPring-8, and started operation.
