Specific: Target 
Subject: Additional targets added to T2-MK1 ladder 

 The following work on the T2-MK1 target was completed sporadically over the last few months:

 

Sept 22:
- T2-MK1 target moved from storage pit to hot cell (new camera view to check flask doors and latch engagement works great)
- Rubber pad from storage pit standoffs was stuck under flange - removed and cleaned base of flange
- Preliminary leak check: target positions and  delta seals no response, left bellows (facing ladder) had tiny response up to 3.0E-8 with recovery in ~5s, right bellows no response
- Removed plugs at Position #1 and #3

Oct 14:
- Installed 12mm Be target #106 at Position 1 (confirmed with Yuri that it may be useful to have a short Be target on the T2 ladder)
- Installed 5cm target #301 at Position 3
- Leak checked target positions: no response, only mild delayed drift
- Position 4 plugs removed

Nov 10:
- Installed 5cm target #302 at Position 4
- Repeated leak check: no response at all target positions
- Took vertical and horizontal measurements for all new targets
- Position limit switches and potentiometer confirmed working ok

Nov 24:
- Moved to Storage Pit Hole #4
