More Information
Summary:A trigger system was designed for the external target experiment in the Cooling Storage Ring （CSR） of the Heavy Ion Research Facility in Lanzhou （HIRFL）. Considering that different detectors are scattered over a large area, the trigger system is designed based on a master-slave structure and fiber-based serial data transmission technique. The trigger logic is organized in hierarchies, and flexible reconfiguration of the trigger function is achieved based on command register access or overall field-programmable gate array （FPGA） logic on-line reconfiguration controlled by remote computers. We also conducted tests to confirm the function of the trigger electronics, and the results indicate that this trigger system works well.
