9/3 DAY Shift: 15:00-23:00UTC (08:00-16:00PDT), all times posted in UTC
Locked @Nominal_Low_Noise for ~12hrs with a range ~65Mpc. Kept H1 in Observation Mode as much as possible (there were a few errant drops & then we stayed down for PEM Injections starting at around noon (PST). I went through the Operator Checklist & completed most of it. I am supposed to check the Visitor Checklist, and it looks fine. I hesitated to check the HEPI watchdog saturation counter, for fear it might add diffs to the SDF (might try it tomorrow).
Remember:
-
AFter lockloss, "INIT" ISC_LOCK (and possibly select DOWN).
-
Re-enable Transient Injections (to make CALCS SDF green), after PEM Injections
-
Make sure SDF is made GREEN after "Commissioning" work (I see HAM6 ISI has some diffs...& I see this is probably related to PEM injections).
-
IP-9 at MY still has HV values around 7kV.
End of shift Control Room Activities:
-
PEM Injections
-
Calibration work (this is post-work from last week and not touching H1).
-
Log of Activities:
-
16:45UTC 250mL added to PSL chiller (Bartlett)
-
17:19 Robert talked with LLO to coordinate dropping out of Observation Mode (plan an hour from now)
-
~18:48 Beckhoff Timing Comparator button accidentally turned OFF/ON by Kissel (BUT, we stayed in OBSERVATION mode since we currently do NOT monitor Beckhoff channels.) The button is at: SITEMAP --> SYS --> Timing --> Corner A --> "11" Active Port button pushed.
-
18:30-19:30 FMCS computer went INVALID. 19:41 signals appeared to start coming back.
-
19:00 Talked with Peter regarding request for starting Transient Injection. Since PEM Injections are starting, we decided to DISABLE the "ting". Will ENABLE when PEM Injections are complete.
-
19:08 Dropped Out of Observation Mode due to SDF diff from DISABLING Transient Injection (!). [Peter Shawhan, Corey]
-
Stayed out of Observation Mode since PEM Injections starting (Observatory Mode taken to Commissioning.) [Robert & Anamaria]
-
19:41 Corner Station Temp is low VerbalAlarm (but this is due to FMCS going down earlier). [Bubba]
-
20:42 Load Coefficients was run for SUSITMX since there were filters added by Nutsinee/Dan for violin mode work. [Dave B]
