In this contribution we present the MicroTCA-based LLRF systems used for the STF-II accelerator. At the same facility a vertical test stand for the R&D of superconducting cavities is operated. The over 20-year-old analog control system is being replaced by a MicroTCA.4-based system. We report on the commissioning status of it. In addition to this an outlook for the planned MicroTCA.4-based...

The vertical test (VT) stand at the KEK Superconducting RF Testing Facility (STF) uses an analog RF control system which is over 20 years old now. We are currently in the process of replacing this old system with a new digital LLRF system based on the MicroTCA.4 architecture. The digital system also allows for greater flexibility regarding configurability and software automation due to the...
