Abstract

In J-PARC 3 GeV Rapid Cycling Synchrotron, the synchronized data system with reflective memory was constructed. However, this system has been operated for more than 10 years, it is essential to take countermeasures against deterioration over time. In addition, this system is difficult to support the large data sizes that have been recently requested. Therefore, we proposed a new synchronized data generation method. The test bench for a new synchronized data system that implements the new method was configured and its performance was verified. This result leads to the development of a new synchronous data system based on data transfer via LAN. In this paper, we describe the outline of the new synchronized data generation method and the results of performance tests.
