一组CsI（纯）晶体已被用作电磁量能器，用于探测光子能量低于1.2GeV的光核反应中的π 0。利用日本国家科学院东京电子同步加速器上的电子束和标记光子束研究了量能器的能量和位置分辨率等性能。在惯性导航系统进行的第一次核相干π 0光生实验中，在π 0能区（0.5 ~ 1.0GeV）获得了7 MeV（rms）的π 0质量分辨率。
A set of CsI(pure) crystals have been tested for use as an electromagnetic calorimeter for π0detection in photonuclear reactions at photon energies below 1.2 GeV. Performances of the calorimeter including energy and position resolution are studied by using the electron and tagged-photon beams at the INS-Tokyo electron synchrotron. In the first experiment for the nuclear coherent π0photoproduction carried out at INS, a π0mass resolution of 7 MeV (rms) has been obtained in the π0energy region between 0.5 and 1.0 GeV.
