摘      要：Beam signals captured from a button-type pickup contain multidimensional information including the bunch charge,transverse position,bunch length,and longitudinal phase.A bunch phase monitor,which retrieves longitudinal phase information from a pickup signal at a bunch-by-bunch rate,has been developed at the Shanghai Synchrotron Radiation *** paper introduces the basic principles,system setup,data processing method,and preliminary experimental results of this *** systematic measurement error introduced by the limited system bandwidth,bunch length,and bunch charge variation was studied using simulation *** random measurement uncertainty was evaluated using experimental beam *** experimental result shows that the longitudinal phase resolution of this system is better than 1.0 *** first application,measuring the relationship between the longitudinal phase and bunch charge to determine the energy loss factor,was implemented,and the preliminary result is also discussed.
