摘      要：A kicker control system is used for beam extraction and injection between two cooling storage rings（CSRs） at the Heavy Ion Research Facility in Lanzhou（HIRFL）. To meet the requirements of special physics experiments, the kicker controller has been upgraded, with a new controller designed based on ARM＋DSP＋FPGA technology and monolithic circuit architecture, which can achieve a precision time delay of 2.5 ns. In September2014, the new kicker control system was installed in the kicker field, and the test experiment using the system was completed. In addition, a pre-trigger signal was provided by the controller, which was designed to synchronize the beam diagnostic system and physics experiments. Experimental results indicate that the phenomena of “missed kickand “inefficient kick were not observed, and the multichannel trigger signal delay could be adjusted individually for kick power supplies in digitization; thus, the beam transport efficiency was improved compared with that of the original system. The fast extraction and injection experiment was successfully completed based on the new kicker control systems for HIRFL.
