OMC PD became noisy, * Vacuum system: Leak test of the OMC chamber. Leak at Y-arm was due to the CC-10. * Heater control: * TMS: == Post O4a == * Measurements of the DAC noise: The next time on 8/4. * 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: * Hight adjustments of Type-A in the cooling: [[https://paper.dropbox.com/doc/Hight-adjustment-in-cooling--B7ii3omB81JIm6khnBt_7fcaAQ-swWQ5h6M6lSs8yLp5D6dA|The procedure]]. Cooling was started on 7/27. * Noise budget of the suspensions: * Temperature control for the Oplev: Devices of the heater controller are ready. == Discussion ==
