Abstract
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 positro n storage ring. Agreement between the experimental results concerning the rate of impurity growth and a calculation taking account of the re lativistic effects of electron-electron scattering, which is the origi n of the impurity growth, was fairly good. A deformation of the distri bution at a high beam current was observed, and was analyzed phenomeno logically.
