Abort trigger system of SuperKEKB and MPS device of J-PARC MR

Currently, we are developing software and testing boards for the SuperKEKB abort trigger system, as well as improving and developing MPS devices used in J-PARC MR and other systems. The SuperKEKB abort trigger system aggregates over 130 beam abort request signals and records the reception time of each signal as a timestamp. These recorded timestamps are used to investigate the cause of beam aborts. We are continuing to test the boards and will proceed with system construction in the future. Additionally, we have added a function to record information when the MPS activates in the MPS devices used in J-PARC MR and other systems. Considering the difficulty of maintaining and operating the currently used CPU modules in the future, we are developing new CPU modules. The prototype CPU module is unstable in operation, so we plan to revise the module by improving the wiring to the memory. (J.P.N.)
