Commissioning calendar for next 2 weeks

Here is the list of commissioning task for the next 7-14 days:

  1. Reduce common length to zero.
  2. Hand-off common mode to to RF.
  3. Retune WFS with TCS ITMX central heating on.
  4. Lock interferometer on OMC.
  5. Search for red resonance sometimes fails.
  6. Check RF power on 2f detectors.
  7. Keep investigating lock losses.

Alignment team:

  1. Make EY green WFS work again.
  2. Model changes to include green WFS feedback to TMS.
  3. Commission an arm alignment controls topology which can be used for initial alignment.
  4. Integrate green WFS into initial alignment.
  5. Revise initial alignment scheme.

Miscellaneous:

  1. Fine tune Michelson contrast defect using ITMY TCS/CO2 laser.
  2. Model changes in SUS for bounce and roll mode damping.
  3. Finish cleanup of ISI controllers (BSC2/10).
  4. Use HWS to check thermnal lens.
  5. Investigate long-term alignment stability of mode cleaner ISS.
  6. Add an "ISS engaged" state to the IMC guardian.
  7. Implenment updated tidal compensation/length relief strategy.

RF:

  1. Make an assessment of RF cross talk into the IMC AOM.
  2. Investigate EMI radiation by the VCOs and the fixed frequency OCXO.
