CHETA VP added to Y-arm Adapter Plate. VP for ITMY IR camera moved up.

Gerardo, Camilla, Mitchell

Gerardo and I removed the blank from the Y-arm adapter plate A-1F VP2 (T1200220) and swapped the D2000285-v2 type 01 SN 005 nozzle baffle to D2000285-v2 type 07 SN 002 nozzle baffle plate Mitch had prepared, all existing hardware reused and orientation kept the same. Photos before and after attached.  

The fused silica VP for the ITMY IR camera (not currently used for locking of in NLN but we want to keep) was then moved up to this A-1F VP2 location. The camera can itself does not fit on without modification, it is ~1-2" too long to fit inside the Oplev pier, so a yellow VP cover was installed while this is done. 

A D1700340-type002-003 VP assembly (D1700338 SN 003, D1700339 SN 003, D1700342 SN1) for CHETA with ZnSe windows (D1100439-type02-002 0.5" thick AR 1064nm, 10.6um and D1100485-tyoe03-005 0.25" thick AR 1064nm, 4.6um) photo was installed in the lower A-1F VP3. The correct D2000285-v2 type 07 nozzle baffle plate with a 2" aperture was already installed, photo
