Post O4a
- Measurements of the DAC noise: Every Friday from 7/7.
- Measurements on the sensor correction in SR2: 1 night.
- Optimization of the damping control in PRs: Measurements 2 days, Test 3 days.
- IP control with the ACCs: Postponed the long-term test in IY.
- In-vacuum accelerometer for IOO: Installed the geophone pod into the OMC chamber on 7/10.
Hight adjustments of Type-A in the cooling: Confirm the procedure.
- Check of the length Oplev:
- Noise budget of the suspensions: Identified the peak frequencies. Peaks in BS don't match the model.
- Temperature control for the Oplev: Preparing for the heater controller.
