      5. If good, repeat (2) (3) until you encounter (4-2). If bad, select opposite actuation then repeat (2)(3) until you encounter (4-2) again.
      6. If you find max point, perform (1)~(5) forPitch/PR2/IMMT2. (1)~(6) is regarded as one “set” optimization.Ideally, it is better to perform 2 sets for each Yaw/Pitch.

  12. X arm IR alignment (GR/IR resonance check).

    • Go to Commissioning.Doc.

    • Select "SEMI AUTO ALIGNMENT" in Commissioning.Doc.

    • Select "Align Xarm" in SEMI AUTO ALIGNMENT.

    • Wait until auto alignment seems to be stable.
    • Select left “!record” for GR, select“!record” for IR.
    • Select “Disable Xarm”

  13. X arm GR/IR alignment Established.

  14. Y arm IR alignment Preparation.

    • Go to Guardian Overview.

    • Select "VIS_ITMY" in Guardian Overview.

    • Select "request [All]" in VIS_ITMY.

    • Select "ALIGNED" in All.

    • Select "VIS_ITMX" in Guardian Overview.

    • Select "request [All]" in VIS_ITMX.

    • Select "MISALIGNED" in All.

  15. Y arm IR alignment (Resonate IR).

  16. Y arm IR alignment (Check spot position on ETMY).

  17. Y arm IR align (Adjust BS for ETMY spot centering).

    • Go to Commissioning.Doc.

    • Select "ALL VIS" in Commissioning.Doc.

    • Select Bs "OVERViEW" in ALL VIS.

    • Select "OLSET OPTIC" for BS in OVERVIEW for BS.

    • You can find for BS. Right click on slide bar and select “-1” as an increment. Never select large increment.

    • Adjust Pitch and Yaw to set the beam spot around the center of ETMY with eyeball on http://172.16.33.39/vacuum.

  18. Y arm IR alignment (ITMY,ETMY alignment).

    • Go to Commissioning.Doc.

    • Select "ALL VIS" in Commissioning.Doc.

    • Select "CRY-P" for both ITMY and ETMY in ALL VIS.

    • Select "OL SETPOINT" for ITMX and ETMX in CRY-P.

    • You can find for both ITMX and ETMX. Right click on slide bar and select “-1” as an increment. Never select large increment.

    • Maximize K1:AOS-TMSY_IR_PDA1_OUTPUT by adjusting, firstly Yaw of IETMY and secondly Pitch.

      1. Remember the value of K1:AOS-TMSY_IR_PDA1_OUTPUT (assuming VtmsyIR-0).

      2. Anyway, move Yaw/ETMY in one direction until you observe slight reduction of VtmsyIR-0.
      3. Move Yaw/ITMX in both direction to find max of VtmsyIR.
      4. (4-1) If you can find better VtmsyIR than VtmsyIR-0, it means your selection for ETMY actuation is good direction.
        • (4-2) If worse, bad direction.
      5. If good, repeat (2) (3) until you encounter (4-2). If bad, select opposite actuation then repeat (2)(3) until you encounter (4-2) again.
      6. If you find max point, perform (1)~(5) for Pitch/(IE)TMY. (1)~(6) is regarded as one “set” optimization.Ideally, it is better to perform 2 sets for each Yaw/Pitch.

  19. Y arm IR alignment (Check spot on ITMY).

    • Check the position of spot on ITMY. We have no way to set it around the center of ITMY because the spot position on ITMY should be adjusted by suspension. However we don’t do at present. So the position on ITMY is just decided by setting accuracy.

  20. Y arm IR alignment Established.

  21. Y arm IR alignment (Record good TMSY).

  22. Y arm GR alignment (Resonate GR).

  23. Y arm GR alignment (TMSY GR maximize with SR3).

  24. Y arm GR/IR alignment Established.

  25. FPMI Recovery (Exit from alignment mode).

  26. FPMI Recovery (Align ITMX).

  27. FPMI Recovery (Start FPMI).
