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The single-pass BPM electronics at SPring-8 has been replaced by MTCA.4-based electronics.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...
SuperKEKB implements a collision feedback system to maintain stable collision. The system consists of several MTCA boards. This presentation describes the application of MTCA to the feedback system.
We had four RF stations in SPring-8 storage ring. We replaced the NIM module based system to MTCA.4 module based system at RF station A in 2018. The replacement of the LLRF system at other three RF stations were carried out step by step. In this talk, operational experience of MTCA.4 modules will be shown.
The VME system has long been used for accelerator controls in SuperKEKB.
However, since this architecture is now outdated, we have been considering migration to a microTCA-based system.
In this talk, we will present the background and criteria for this transition.
TSPD offers digitizer products with various interfaces. We will introduce the models with MTCA interface, along with application-specific firmware developped for those products.
J-PARC Main Ring (MR) delivers the 30-GeV protons to the particle physics experiment. Microwave instabilities have been observed in the J-PARC MR during both the acceleration for the beam to the neutrino experiment and the debunching process for the beam to the hadron experiment. Since the instability does not occur every shot, monitoring the waveform of the beam signal for every shot is...
The Module Management Controller (MMC) is a critical intelligent controller responsible for managing AMC boards. It communicates with the MTCA Carrier Hub (MCH) via the Intelligent Platform Management Bus Local (IPMB-L). Since 2010, we have been developing MMC software for our AMC and uRTM boards. During development, we encountered challenges related to the complex protocols defined in the...
At the KEK Photon Factory 2.5 GeV ring (PF ring), a new LLRF system was installed in 2023. The new system is composed of digital boards based on the MTCA.4 standard. This presentation will summarise the development of these digital boards.
