Two types of data, synchronized data and non-synchronized data, are utilized on J-PARC Linac and RCS. A synchronized data with beam information (beam tag) is also utilized on SNS, SACLA and other accelerators as the standard data type, recently. To perform J-PARC upgrade toward 1MW beam power, it will become the higher necessity and importance to utilize the synchronized data in the years ahead. At the present, the synchronized data is designed to be provided by Reflective Memory (RM) system and Wave Endless Recorder (WER) system, in J-PARC Linac and RCS. However, the function of synchronization between RM system and WER system has not yet been implemented, and the data synchronization is applied for each accelerator subsystem independently. Therefore, the synchronization has not realized neither between each WER system nor between each accelerator subsystem. In order to synchronize between each WER system and between each accelerator subsystem, Trigger Counter Board (TCB) was designed and developed. This article presents the details of the function of TCB and the synchronization method, and the development status of synchronized function between RCS RM system and WER system.
