Leak test in EYC and EXV. * Heater control: * TMS: == 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 [[https://paper.dropbox.com/doc/Hight-adjustment-in-cooling--B7ii3omB81JIm6khnBt_7fcaAQ-swWQ5h6M6lSs8yLp5D6dA|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. == Discussion ==
