QUAD Testing Outline, Phase 2BFiber Lower “half” Build-up and
TestingM. Barton, B. Bland, D. Cook, J. Kissel, N.
Robertson, J. Romie, T. Sadecki, for the SUS team

Jargon
• Lower “half” / Upper “half”• “Metal” or “Wire” hang vs. “Glass” or “Fiber” hang • Fiducials / References• Parallelism / Differential Pitch• PUM and TST, RPUM and RMCP

G1100769-v2 3
• Install IAS Retro-reflector on Cage• Gather fiducials of metal hang on
BSC-ISI– Height between PUM and TST– Yaw of PUM and TST
Full Metal QUAD on BSC-ISI
G1100769-v2 4
G1100769-v2 5
Detach Lower “Half,” move to Triple Hang Tooling
• Lock Down Both Chains • Prepare LSAT• Detach lower half cabling fom reaction chain
G1100769-v2 6
Separate Chains
• Move separated chains from LSAT to leveled granite / optical table
G1100769-v2 7
TEST MASS CHAINRemove Metal PUM and TST
G1100769-v2 8
TEST MASS CHAINInstall and Test Ring Heater
• Test ring heater functionality
G1100769-v2 9
TEST MASS CHAINInstall Glass PUM
• DC Alignment checks
G1100769-v2 10
TEST MASS CHAINSuspend PUM, Check DC Alignment
• With UIM to PUM Blades EQ stopped, free up PUM• Check prism functionality• Compare DC alignment to metal references• Redo loops, as necessary
• Re-lock PUM

G1100769-v2 13
TEST MASS CHAINFull Fiber Single Pendulum Characterization
• With PUM still on line stops, Unlock TST• Check DC Alignment, compare against metal references• Check PUM / TST Surface 1 parallelism / differential pitch• Measure Pitch and Yaw modes w/ spectra of optical lever• Measure Vertical and Violin Modes with shadow sensor

REACTION MASS CHAINRemove Metal RMCP
G1100769-v2 16
REACTION MASS CHAINInstall Glass RMCP
• Check ESD functionality / electrical properties up to cable break off before installing
• Continuity • Capacitance
G1100769-v2 17
REACTION MASS CHAINSuspend RMCP, Check DC Alignment
• Check DC alignment against references• Check prism functionality• Redo loops if necessary
G1100769-v2 18
REACTION MASS CHAINLace Up RMCP Cables
• Check ESD functionality / electrical properties at RMCP Break off (again)• Lace cables up through remainder of the reaction chain• Check ESD functionality / electrical properties at top the chain
G1100769-v2 19
Marry Chains• Remove First Contact from Test Mass’ Surface 2 (AR Coating), and RMCP Surface 1 (AR / Gold Coating)
G1100769-v2 20
Reinstall to full QUAD on BSC ISI
