Commissioning calendar for next 2 weeks

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

Locking team:

  1. Fix ALS DIFF feedback path (ESD/SUS crossover).
  2. DRMI stability with new 3f detector modification.
  3. Check RF power on 2f detectors.
  4. Carrier sweeps with DRMI locked o new 3f.
  5. Common hand-off to transmitted power.
  6. Lock interferometer.
  7. Resolve down stream clipping issues in the SRC.

Modecleaner team:

  1. Investigate long-term alignment stability of mode cleaner.
  2. Minimize intensity noise coupling through mode cleaner.
  3. Optimized auto alignment scheme to minimize coupling.

Alignment team:

  1. Revisit EY green WFS beam path and look for ghost beams.
  2. Make EY green WFS work again.
  3. Install EX green WFS auto-centering hardware.
  4. Commission an arm alignment controls topology which can be used for initial alignment.
  5. Integrate green WFS into initial alignment.

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.
