介绍了J-PARC快速循环同步加速器束流诊断系统的研制。该系统由束流位置监测器(BPM)、束流损失监测器(BLM)、电流监测器(DCCT、SCT、MCT、FCT、WCM)、调谐监听系统、324 MHz-BPM、轮廓监测器和光晕监测器组成。BPM是静电型的，其电子学设计既可用于COD测量，也可用于逐圈测量。为了覆盖较宽的频率范围，五种电流监测器具有不同的时间常数。调谐监测器由激励器和束流拾取电极组成。对于连续注入束流监测，324 MHz-BPM检测直线加速器频率。两种类型的轮廓监测仪是用于低强度调谐的多线式和用于无损测量的残余气体电离监测仪。
Development of the beam diagnostics system for the J-PARC Rapid-Cycling Synchrotron is described. The system consists of Beam Position Monitor (BPM), Beam Loss Monitor (BLM), Current monitors (DCCT, SCT, MCT, FCT, WCM), Tune monitor system, 324MHz-BPM, Profile monitors, and Halo monitor. The BPM is electro-static type and its electronics is designed for both COD and turn-by-turn measurements. Five current monitors have different time constants in order to cover wide frequency range. The tune monitor is consisted of the exciter and the beam pick-up electrode. For the continuous injected beam monitoring, 324MHz-BPM detects Linac frequency. Two types of profile monitor are multi-wire for low intensity tuning and the residual gas ionization monitor for non-destructive measurement.
