TI - HEPS Storage Ring BPM Development J2 - Proc. of IBIC2020, Santos, Brazil, 14-18 September 2020 CY - Santos, Brazil T2 - International Beam Instrumentation Conference T3 - 9 LA - english AB - Beam Position Monitors BPM is the most important and frequent non-destructive diagnostics used at nearly all synchrotrons. In HEPS project, the BPM electronics have been developed all by the BI group staffs. There are 4 main parts are involved in development: the hardware of AFE (RF analog circuit) and DFE (Digital signal processing circuit), the firmware of algorithm, the data acquisition software (DAS), and the BPM testing system. In order to get a better performance, the RF analog circuit (AFE) is design carefully, and the algorithm (HDL in DFE) has been designed and optimized. At the same time, several related techniques are studied to improve the system long-term resolution, such as the thermally controlled racks, 2-way analog switching, the thermal compensation algorithm, etc. Moreover, testing system for BPM is a very important during the BPM electronics development, in manufacturing stage, it can provide the testing tools for the hardware and firmware. And in system running stage, it can be used for a diagnose tools, calibration tools, and monitoring tools for the BPM system. So the BPM testing system can make the system more robust.
