1 QUAD Testing Outline, Phase 2B Fiber Lower “half” Build-up and Testing M. Barton, B. Bland, D. Cook, J. Kissel, N. Robertson, J. Romie, T. Sadecki, for the SUS team G v2

2 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 G v2 2

3 Install Glass RMCP Lace ESD Cables up Chain Re-test, (as needed) Remove First Contact from Surface 1 Functionality Test RH Install Ring Heater Weld & Anneal Fibers Install Glass TST Order of Operations Full Metal QUAD on BSC ISI Metal Triple Hang Both Chains Remove Metal PUM and TST Mass Separate Chains TEST MASS CHAIN REACTION MASS CHAIN Install Glass PUM Suspend PUM Only, Perfom DC Prism Checks DC Alignment Checks Suspend TST Only, Single Pendulum Full Characterization Re-anneal Fibers (as needed) Install Fiber Guard, Central Fin Remove Metal RMCP Mass Suspend RMCP, DC Prism Checks Functionality Test ESD, UIM, PUM AOSEMS Remove First Contact from Surface 2 Marry two chains On to Phase 2C Re-Install to full QUAD on BSC ISI DC Alignment Checks DC Alignment Rubbing Checks G v2 3

4 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 G v2 4

5 5 Detach Lower “Half,” move to Triple Hang Tooling Lock Down Both Chains Prepare LSAT Detach lower half cabling fom reaction chain

6 G v2 6 Separate Chains Move separated chains from LSAT to leveled granite / optical table

7 G v2 7 TEST MASS CHAIN Remove Metal PUM and TST

8 G v2 8 TEST MASS CHAIN Install and Test Ring Heater Test ring heater functionality

9 G v2 9 TEST MASS CHAIN Install Glass PUM DC Alignment checks

10 G v2 10 TEST MASS CHAIN Suspend 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

11 G v2 11 TEST MASS CHAIN Install Glass Test Mass

12 G v2 12 TEST MASS CHAIN Weld and Anneal Fibers

13 G v2 13 TEST MASS CHAIN Full 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

14 G v2 14 TEST MASS CHAIN Install Fiber Gaurds

15 G v2 15 REACTION MASS CHAIN Remove Metal RMCP

16 G v2 16 REACTION MASS CHAIN Install Glass RMCP Check ESD functionality / electrical properties up to cable break off before installing Continuity Capacitance

17 G v2 17 REACTION MASS CHAIN Suspend RMCP, Check DC Alignment Check DC alignment against references Check prism functionality Redo loops if necessary

18 G v2 18 REACTION MASS CHAIN Lace 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

19 G v2 19 Marry Chains Remove First Contact from Test Mass’ Surface 2 (AR Coating), and RMCP Surface 1 (AR / Gold Coating)

20 G v2 20 Reinstall to full QUAD on BSC ISI

21 G v2 21 DC Alignment, Rubbing Checks of Both Chains
