描述了一种磁谱仪，用于标记康普顿后向散射激光从存储环中循环的电子束中产生的伽马射线束。现在安装的光谱仪的设计能量分辨率为5.5 MeV，色散为2.8 MeV/cm，动态范围为160 MeV。能量分辨率受存储光束能量扩散的限制。如果在存储环的激光-电子相互作用直线段引入色散，则根据色散的大小，可以将分辨率提高到1.5 MeV。该光谱仪的测量性能与设计值基本一致。
A magnetic spectrometer is described for tagging a gamma-ray beam produced by Compton backscattering laser light from the electron beam circulating in a storage ring. The spectrometer, as it is now installed, has a design energy resolution of 5.5 MeV, a dispersion of 2.8 MeV/cm, and a dynamic range of 160 MeV. The energy resolution is limited by the energy spread of the stored beam. If dispersion can be introduced into the laser-electron interaction straight section of the storage ring, the resolution can be improved to be as small as 1.5 MeV, depending on the value of this dispersion. Measured properties of the spectrometer are in substantial agreement with the design values.
