光子标记系统，确定每个光子的能量在韧致辐射过程中构建，并使用提取的电子束从1.3 GeV的电子同步加速器在核研究所，东京大学进行测试。该系统由一个分析磁铁和25个标记计数器组成，可检测能量范围为100 MeV至350 MeV的反冲电子。用全吸收型铅玻璃切伦科夫计数器标定了每个标记光子的能量。用切伦科夫计数器测量的能量与由反冲电子轨道计算的能量在±10 MeV的误差范围内吻合得很好，首次实验表明，标记光子束的强度被限制在105光子/s。
A photon tagging system which determines the energy of each photon in the bremsstrahlung process is constructed, and is tested using an extracted electron beam from the 1.3 GeV electron synchrotron at the Institute for Nuclear Study, University of Tokyo. The system which consists of an analyzing magnet and twenty-five tagging counters detects the recoil electrons in the energy range from 100 MeV to 350 MeV. The energy of each tagged photon has been calibrated with a total absorption type lead glass Cerenkov counter. A good agreement within the error of ±10 MeV is obtained between the energy measured by the Cerenkov counter and the one calculated from the trajectory of the recoil electron. From the first experiment using this system, it is found that the intensity of the tagged photon beam is limited to 105 photons/s.
