In the first part of the shift the TCS group continued the test started in the morning; the activity was concluded at ~19:30 LT. After that the ITF was relocked at step12 e put in standard condition.
In agreement with the request the ITF was left in Science mode and the autorelock has been enabled.
TCS
To perform the test one photdiode on NI TCS bench has been removed (see dedicated entry for more details) and as consequence the NI TCS laser is seen as OFF by the DMS (red flag); for this reason the subflag has been muted.
To perform the test the NI rotator servo loop was also switched off; it was restarted but the loop seems to work not properly (see figure1). Experts on site have been informed.
