The shift was dedicated to the planned ISC/OSD activity (Arms cavities analysis of 6 MHz SB in CITF, study of asymmetry between Warm and Narm measurement, OMC scan), carried out by Cabrita, Casanueva, Boldrini, Spinicelli.
During the first part of the shift we performed the measurements with the initial CHRoCC DAC_V value (0.43). Here is the list of the performed measurements:

6:58 UTC - Free Specral Range Scan while in LOCKED_ARMS_BEATING, command CARM_SET_scan_FSR(6);
7:04 UTC - Cavities Scan Matching, command SCAN_TEMs_TOT(1) (see attached plot #1);
7:39 UTC - 5 minutes of CITF Locked;
7:52 UTC - CARM SET Scan in CITF;
From 8:26 UTC to 8:47 UTC - OMC Scan with the remote support of Gouaty (see attached plot #2);

After this last measurement, at 9:12 UTC we changed the DAC_V of the CHRoCC PR from 0.43 to 0.41. After waiting 90 minutes we attempted again the measurements, starting from the CARM SET Scan in CITF, but the ITF unlocked after a few minutes. Here the timetable of the other measurements carried out with this configuration:

11:23 UTC - 5 minutes of CITF Locked; 
From 11:33 UTC to 11:55 UTC - OMC Scan; (see attached plot #3).
12:04 UTC - CARM_SET_scan_FSR(6) 
12:14 UTC - SCAN_TEMs_TOT(1) (see attached plot #4).

Completed this second set of measurements, we adjusted again the CHRoCC DAC_V, from 0.41 to 0.39. We waited 90 minutes and started the third set of measurements:

14:11 UTC - CARM_SET_scan_FSR(6);
14:16 UTC - SCAN_TEMs_TOT(1) (see attached plot #5).
From 15:06 UTC - OMC Scan.

OMC Scan in progress.
