Development of data synchronization system for the LINAC/RCS in J-PARC

Kawase, Masato*; Takahashi, Hiroki ; Kato, Yuko; Kikuzawa, Nobuhiro ; Ouchi, Nobuo 

The data acquisition in J-PARC LINAC/RCS are two methods of data archiving of polling data via EPICS Channel Access and synchronized waveform data. The synchronized waveform data are collected by several Wave Endless Recorders (WER). The WER counts the trigger number and holds waveform data in a ring buffer memory. We developed a Trigger Counter in order to manage the trigger number of each WER and synchronize the trigger number of each WER via LAN. At present, in order to install the waveform data synchronization system, we carried out verification using the timing test bench. This report presents about the waveform data synchronization system and future plan of the data acquisition system.
