The 3GeV proton beam transport facility (3NBT) is a high-intensity proton beam line from the 3GeV Rapid Cycling Synchrotron (RCS) to the Material and Life science Facility (MLF) at Japan Proton Accelerator Research Complex (J-PARC). In order to allow hands-on maintenance, a design criterion has been that the average beam loss at 3NBT be less than 1W/m. The systems for beam monitoring and magnet power control play an important role. In J-PARC, the Experimental Physics and Industrial Control System (EPICS) [1] will be used for the main control system. For the proton beam monitor system of 3NBT, EPICS is used and it has to work at 25Hz. In this study, a data acquisition system for the proton beam monitors is presented that has been developed with EPICS. Its performance has been investigated under 25Hz frequency condition.

The 3GeV RCS injects each beam pulse of 25 Hz into the MLF and the 50GeV MR in a predefined order. Then, in monitoring and control for RCS, some data is required the synchronicity. On the other hand, some data is not required the synchronicity. Therefore, in RCS control system, the development of a data acquisition system which records these two kinds of data efficiently is indispensable. Then, we categorized the data which is required synchronicity as "fast synchronized data" and "slow synchronized data". And, we categorized the data which is not required synchronicity as "standard data". So, we designed and developed the DAQ system configuration for each categories data. In addition, we design and develop the DAQ system to simultaneously collect the three categories data and to provide users the three categories data which are collected and matched. The status of development for RCS DAQ system will be presented in this report.
