The cryomodule itself was downgraded by RF in SRM on the 15th, but the cavities have the green thumb. Turning off until SRM is updated for the zone.

Follow-up Re: Hall A Laser AMP Output Power (died)

11 hours ago
Log Number: 4471183Logbook(s): Body: 

After some diagnostic work, it was found the seed laser was indeed dead (something rarely happened), it's not a simple system trip off. There was no power coming out at all from the seed laser board. With the help from Steve, I replaced the seed laser board with a spare. Tuned up the seed and pre-amp to bring up the input power to the power-amp to about 2mW. Also adjusted the photodiode level for both seed and pre-amp to be consistent with other lasers. There was no issue turning on the A pow-amplifier afterwards. The system works fine now.

LLRF Pre-Commissioning for Cavities:

We verified all interlock checks (ARC, window, vac, HE interlock faults) and all passed without issue.
We also put a small amount of forward power into each cavity in SEL mode. We found each cavity to be off machine reference. These are the results for each cavity:

cavity 1, 150k
cavity 2, 126k
cavity 3, 83k
cavity 4, 117k
cavity 5, 90k
cavity 6, 90k
cavity 7 ,120k
cavity 8, 98k

We did not attempt to tune the cavities. We will do this after coordinating with SRF (likely 2/17/26 afternoon).
