Abstract J-PARC Main Ring (MR) is there are two operation modes of the fast extraction (FX) and slow extraction (SX). The SX operation used the spill control system. It consists of two kinds of Extraction Quadrupole Magnet (EQ), Ripple Quadrupole Magnet (RQ) and Spill Control Device with Digital Signal Processor (DSP) which calculates and controls it the optimal current pattern using the monitor signal of an extraction beam. It is used to make flatten the extraction beam structure and reduce the ripple noise. The present Spill Control Device needs to be reviewed from the aspect of service life etc. In this presentation, we will focus on improving the versatility of the device and the operability of the DSP program, and explain the development of the next-generation spill control device.
