The first application of MTCA at J-PARC is the RCS LLRF control system, which was deployed in 2019. Since then, the number of the applications at J-PARC is steadily increasing. The LLRF control systems for MR and Linac are now fully operational. We have several future applications, for example, the digitizer for Linac beam loss monitors and the timing system. The status and future plan of the...
A LLRF control system for a synchrotron based on MTCA.4 has been developed and operated at WERC. The system was replaced old one consisted of DDS (Direct Digital Synthesizer), DSP (Digital Signal Processor) and analog RF circuits. The new system consists of three AMCs. One is for feedback control of RF frequency and the others are for processing beam position signals. In 2018-2019, we designed...
The single-pass BPM electronics at SPring-8 has been replaced by MTCA.4-based electronics. BPM signals are processed by an RTM and sent to a high-speed digitizer AMC. The BPM signal has an RF component synchronized to the acceleration RF frequency of 508.58 MHz. This component is extracted from the filter on the RTM, the signal level is adjusted, and the RF signal is directly sampled by the...
