摘　　要：The Cooling Storage Ring(CSR)external-target experiment(CEE)will be the first large-scale nuclear physics experiment at the Heavy Ion Research Facility in Lanzhou(HIRFL).A beam monitor has been developed to monitor the beam status and to improve the reconstruction resolution of the primary vertex.Custom-designed pixel charge sensors,named TopmetalCEEv1,are employed in the detector to locate the position of each particle.Readout electronics for the beam monitor were designed,including front-end electronics utilizing the Topmetal-CEEv1 sensors,as well as a readout and control unit that communicates with the DAQ,trigger,and clock systems.A series of tests were performed to validate the functionality and performance of the system,including basic electronic verifications and responses toαparticles and heavy-ion beams.The results show that all designed functions of the readout electronics system work well,and this system could be used for beam monitoring in the CEE experiment.
