COMMENT ON HOM Measurement on 2L25 Cryomodule

1 day 4 hours ago
Log Number: 4476613Logbook(s): Body: 

After discussing with Accelerator and SRF Operations the best timing for this measurement will either be during the YB magnet swap sometime mid-April or during the low to high energy reconfiguration in late May. Someone from SRF Operations needs to be involved with the measurement for their understanding of CEBAF.
