Here we report the details of the DAS actuation tests during the yesterday shift. The same power has been applied on both benches.
Test | Start (UTC) | End (UTC) | Power IN (mW) | Power OUT (mW) |
1 | 16:04 | 16:06 | 200 | 400 |
2 | 16:24 | 16:40 | 100 | 200 |
3 | 16:45 | 17:33 | 150 | 300 |
4 | 17:33 | 17:52 | 175 | 350 |
-- | 18:04* | 19:25* | 100* | 200* |
5 | 19:40 | -- | 125 | 250 |
*during this measurement the WI laser changed its working point, so the data are not reliable (grey area in the attached plot).
In the white areas the DAS was OFF.
The selected working point (test 5, probably close to the best one) allowed to keep the ITF locked for the all night.
