摘　　要：A noninvasive Ionization profile monitor(IPM)consisting of micro-channel plates,a phosphor screen and the optical-signal acquisition has been developed at the cooling storage ring of Heavy Ion Research Facility in Lanzhou(HIRFL-CSR).It makes the real-time profile measurements for the transverse beam cooling and orbit oscillation possible and efficient.This paper firstly describes all the IPM design criterions including the theoretical signal yield calculation,the space charge field and initial momentum evaluation,and the electrostatic field distortion simulation as well.In order to investigate the IPM performance,the beam profile measurements are done with different high voltage settings.Subsequently,some valuable beam experiments about the transverse electron cooling and orbit oscillation study are also presented.In the end,fast turn-by-turn profile measurements for the emittance blow-up research in a synchrotron are discussed.In cooperation with the newly deployed emittance instruments at the HIRFL-CSR injector,the IPM shows great prospects for the injection mismatch study,and potential values for the tune,dispersion and chromaticity measurements as well.
