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However, since this architecture is now outdated, we have been considering migration to a microTCA-based system.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.
