3. Capture Cavity II at Meson (@4.5K, no beam) Running closed loop with FB gain of 12 Running open loop and modifying the cavity resonance frequency using the piezo actuators 37% 1.04 ms (153 Hz) Measurement of the cavity half bandwidth ~153 Hz

4. Capture Cavity II at Meson (@4.5K, no beam)  What we’ve achieved so far: Run closed loop, but with a feedback gain of 12 only (issue under investigation) LLRF support for some cryo tests (impact of RF power on cryo bath temperature) LLRF support for piezo tuner measurements  What our near term goals are: Achieve a higher feedback gain  upgrade SIMCON3.1 firmware  run at 1.8K  revise SIMCON3.1 hardware to reduce noise (ADCs, I/O, Power supply, external clocks…) Run CCII using SNS-LLRF system  What our long term goals are: Collaboration with DESY for the next generation SIMCON board R&D for an FNAL-LLRF system suited for ILC specs
