Gluing configuration

►Tip/Tilt Suspensions

Compliant Eddy Current Damping in 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.

[https://dcc.ligo.org/cgi-bin/private/DocDB/ShowDocument?docid=7074 Bram's TT assembly document on the dcc]

[http://ilog.ligo-wa.caltech.edu:7285/advligo/Tip-Tilt_Stage/Tip-Tilt_Mechanical_Design Bram's TT wiki / drawings]

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

Viton Damper Mount

There was a problem of the backplane. A beam of the backplane blocked the laser light goes through the TT optic. attachment:TT_crosssection.png

The design has been modified to address this issue. The modified design is here. attachment:TT_ECD_Drawings_for_40m_100215.pdf

Baking order to Bob: attachment:TTparts_2010-03-11_K_Arai.xls

Magnets: 10mm dia. 10mm thick SmCo magnet pressed in the mirror holder.

Wires: <200um musical wire for the mirror suspension / Bram will give us tungsten wires.

Titanium screws: We try grade 3 cheap Ti screws (#2-56 3/8") ~$1.3ea (c.f. McMaster ~$15ea)

To Do: Wire Jig drawing

►Other suspensions

We will realign the MC suspensions so that we are centered on the mirrors this time.

The PRM, SRM, and BS will remain SOS. No new towers.The ETMs will be replaced to the SOSs later. They exist on the flow bench at the Yend.
