We uninstalled everything on HAM4.

The followings were bagged and labeled for later reuse for aLIGO itself as well as aLIGO related researches at here and elsewhere:

• AS path steering mirrors and periscope
• POB path steering mirrors and periscope
• POX path steering mirrors and periscope
• Squeezing path steering mirrors
• First article aLIGO Faraday
• H2 iLIGO Faraday which was used as H1 SQZ faraday
• Black glass beam dumps

These are all stored in plastic bins and are temporarily put in the ALS/SQZ work area.

There was a mirror-like thing mounted on one of the side viewports from inside. What is this? It was bagged, but if there's no taker I'll throw it away.

The beam reducing telescopes were roughly wrapped with foils and left in the clean room. Store them wherever you want.

All counter balance masses will go to the recycle bin.

HAM5 baffles was not removed this time.

Corey will post pictures, Sheila will notify Carolyn which iLIGO parts are kept.
