Discussion

  • Schedule estimation for commissioning.
    • Necessary term for each task:
      • Y arm lock with green light: 1week
      • TF measurement for hierarchy control: 2-4weeks, depending on fluctuation of mass
      • Type A payload matrix diagonalize: 2-4weeks, after cooling down
      • Y arm lock with mass feedback: 1week
      • X arm lock with green light: 1week
      • FPMI lock: 1week
    • Example1:
      • 3/20-3/27: ETMY TF measurement for hierarchy control 1.
      • 3/27: ETMY cooling start
      • 4/23: ETMY cooling done
      • 4/22-5/10: ETMY TF measurement for hierarchy control 2.
      • 4/25-5/17: ETMY payload matrix diagonalize
      • 5/7-5/10: Y arm lock with green light
      • 5/20-5/24 Y arm lock with mass feedback to ETMY
      • 4/1: ETMX cooling start
      • 4/28: ETMX cooling done
      • 4/29-5/10 X arm lock with green light
      • 5/27-31: FPMI lock
      • when both ends are not available: DRMI lock acquisition. It will be done by 5/31
      • 6/3~ DRFPMI lock acquisition
    • Example2: Needs ETMI tuning after FPMI commissioning
      • 3/25-3/29: Y arm lock with green light
      • 4/1: ETMY cooling start
      • 4/26: ETMY cooling done
      • 3/29: ITMY cooling done
      • 4/1-4/26: ITMY TF measurement for hierarchy control 2.
      • 4/1-4/26: ITMY payload matrix diagonalize
      • 5/7-5/10 Y arm lock with mass feedback to ITMY
      • 4/1: ETMX cooling start
      • 4/28: ETMX cooling done
      • 5/7-5/10 X arm lock with green light
      • 5/13-17: FPMI lock
      • when both ends are not available: DRMI lock acquisition. It will be done by 5/17
      • 5/20~ DRFPMI lock acquisition
