Abstract

When measuring a bunch shape of H-minus beam with the bunch shape monitor (BSM) based on a transverse scanning of low energy secondary electrons the difficulties due to presence of detached electrons arise. Fraction of the detached electrons gets into the optical channel of BSM and produce additional signals thus distorting measurement data. The results of simulation of interaction of the electrons with the BSM target and analysis of their subsequent motion in BSM electron optical channel are presented. Distortions of the measurement results are discussed. It is demonstrated both by simulations and experimentally that energy separation of the electrons essentially decreases the distortions. Other possible reasons of errors are also discussed.
