Description
Summary:The Taiwan light source (TLS) uses a photon beam intensity system (Io monitor) to index the electron beam stability. This index combines the information of the fluctuations of electron beam position and size. For understanding the impact of these fluctuations to the electron beam instability, a set of the optical diagnostic system was installed in the TLS BL10 diagnostics beamline. This system includes the photon beam position monitor (PBPM), the beam size monitor (BSM) and the Io monitor. From the result, we concluded that about one-third impact of beam instability came from the fluctuation of electron beam position and about two-thirds impact of beam instability came from the fluctuation of electron beam size. The hardware configuration is described in this paper.
