Description
At the SuperKEKB storage rings, a special stripline BPM is used at the injection points to measure the injection beam arriving from the beam transport line after it traverses all septum magnets, just before entering the storage rings. A new readout device based on the RFSoC platform and tailored to this application has been developed, successfully deployed and continuously operated during SuperKEKB operations since November 2025. The main motivation for this development was the clean, independent measurement of both 96 ns spaced bunches in the so called two-bunch injection mode, where two bunches are injected in one injection cycle. A secondary objective was, however, to also collect experience with the RFSoC platform towards future in-house developments at KEK. This presentation will summarize the important aspects of the development and evaluation of the developed device, the details of which are described in our previous publication, as well as report on the recent operations and future plans and considerations towards possible deployment to further locations at the beam transport line where performance of the present readout devices is poor.
