COMPLETED & RESUBMITTED C100 stub tuning
Resubmitting for approval. Plan is to start measuring and adjusting Qext as needed to reach target of 1.5e7 on C100 zones. Qext measurements would start on NL as soon as Helium and shield temperatures allows it. As suggested by J. Benesch we need to determine if 4K Helium temperatures is a suitable temperature to work the Qext adjustments. We do have 1L23 as reference since we did stub tunning work while @ 2K last SAD. We can start measuring Qext there and decide how to proceed.

COMMENT ON Injector Beamline Repairs: Winter 2022 SAD
Phil found a tiny leak in the gasket for the harp we installed Wednesday.
We removed the harp to change the gasket and broke a harp wire during the reinstall.
Re-wired the harp (borrowing Tony's wire - thanks!), installed again, checked for shorts, and pumping down now.
harp gasket leak fix
Harp installed on Wednesday. Found a leak yesterday in the gasket.
vented and removed harp to replace gasket today. During replacement, gasket slipped and broke harp wire.
Re-strung harp with wire from Tony.
Checked for shorts on insertion and retraction - seems ok, but manual retraction was causing the fork to vibrate and there was a tiny intermittent short - we'll have to verify that there are no shorts during normal operation with the controller.
Repaired harp reinstalled, tightened gasket, pumping down.
