Application of RFSoC Technology for Beam Position Monitors at the SuperKEKB Storage Rings Injection Points

B. Urbschat, G. Mitsuka, L. Ruckman

In order to achieve its ambitious luminosity target, the SuperKEKB collider must achieve and sustain high beam currents on the order of Ampere in its storage rings. This requires c…
