Etc
- Check SR2-SR3 duct (since Mirapro moved it) to see if we have adequate space at both ends.
- Help crane inspectors on Monday and Wednesday mornings.
- Shut down all electronics before leaving on Friday.
- Update electronics items lists to reflect removed ADC stuff.
- Inspect all crane slot curtains (SR, BS, PR), note which are missing, and decide which should be closed up immediately versus later. (For example, SR2 and SR3 have missing curtains that could be replaced semi-permanently because we probably don't need to crane stuff into those areas anymore.)
SR2 (highest priority)

- Set damper height.
- Crane suspension into tank
SRM (as time permits)
- Set up pitch-setting OL.
- Add TM OSEM cables.
- Set TM pitch and tighten clamps.
- Set RM pitch and tighten clamps.
- Remove winch system and restore items removed from top of IM.
- Install feedthroughs on AF.
