KEK PF正电子存储环中安装并改进了光子计数系统，用于测量束团的时间结构，例如单束杂质和电子的纵向分布。关于杂质生长速率的实验结果与考虑了作为杂质生长根源的电子-电子散射的相对论效应的计算之间的一致性相当好。观察到高束电流下分布的变形，并进行了现象学分析。
A photon counting system for measuring the time structure of bunches, such as the single-bunch impurity and the longitudinal distribution of electrons, was installed and has been improving in the KEK PF positron storage ring. Agreement between the experimental results concerning the rate of impurity growth and a calculation taking account of the relativistic effects of electron-electron scattering, which is the origin of the impurity growth, was fairly good. A deformation of the distribution at a high beam current was observed, and was analyzed phenomenologically.
