Most of this stuff needs to visit Bob's lab for cleaning. 30 Oct 2009 - Screws for EQ stops ordered. Also, fixtures should be sent from MIT ~today, so we should get them soon. 3 Nov 2009 - Most of the screws for EQ stops have arrived (a few were backordered, and will be here shortly). Now I need to drill them / have the shop drill them for the viton. 5 Nov 2009 - Most of the 6-32 screws have been drilled for the viton. The 1/4-20 3/4" screws have arrived, but the 1/4-20 1.5" screws won't be here until early December. |

ITM Suspensions
The ITMs are being changed into SOS. For this we will need to fab 2 SOS towers. We will re-use existing OSEMs and misc in-vac hardware.
SOS Updates (Mostly ITMs, but where applicable, extra parts for other new Optics):

Tip/Tilt Suspensions
For the PRC/SRC folding we will use Tip/Tilt stages modified to be used passively. No active damping, no coil drive. Just magnets and natural eddy current damping.
We have got five initial TT delivery. 4 is for the PRC/SRC folding. 1 is for tests/spare. We would employ 4 more TTs for the Input/Output steering, though we should seriously consider the foot prints of them.

We will employ vertical springs designed by Valera@LLO. Mike@LLO suggested the items additionally needed for attaching the vertical springs.

We will re align the MC suspensions so that we are centered on the mirrors this time.
Others
The PRM, SRM, and BS will remain SOS. No new towers.
The ETMs will remain MOS. No new towers.
