After having waited for the stabilization of NI/WI lasers power needed because of the replacement of the WI backup chiller, we increased the CO2 actuators power of about 25% wrt the previous values in order to follow the input power increase from 12W to 15W (+25%). This action allowed to reach the steady state at the beginning of the afternoon shift.
At 10.45 UTC we started to change the powers. The previous and the current values are shown in the following table:
| CH [W] | INNER DAS [W] | OUTER DAS [W] | ||
| W | on the ITF | 0.042 → 0.053 | 0 | 1.38 → 1.73 |
| on the pickoff | 0.258 → 0.326 | 0 | 0.225 → 0.282 | |
| N | on the ITF | 0.050→ 0.063 | 0.135+0.080=0.215 →0.17+0.080=0.250 | 0.86+1.80 =2.66 → 1.08+1.80=2.88 |
| on the pickoff | 0.308 → 0.39 | 0.022+ 0.013 = 0.035→ 0.028+0.013 =0.041 | 0.14+0.293=0.433 → 0.176+0.293=0.470 |
At 10.58 UTC all the flip mirrors were restored in the proper configuration to be able to start the lock acquisition after the INJ recovery.
