TITLE: 05/30 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY:
Work for H1 continues with H1 making it to DC Readout!
Alignment is NOT "ready for primetime" yet. There are issues with PRX, so one needs to do a Manual Initial Alignment and be careful around the PRC.....basically, go to PRX_LOCKED and tweak PRM to maximize ASC-AS_A_DC. (Since I had issues with one of my alignments, I made notes for aligning next time and they are at the bottom of this entry. Ibrahim is already working on an alignment now.)
LOG:
- 1450-1510 Reset Green references (sheila remotely)
- As Sheila drove in, she said I could run an alignment. Had to Run a Manual Alignment because she mentioned issues with WFS for PRC.
- 1512-1600 Manual Alignment.
- Alignment was mostly straightforward, but I think I missed what to do for PRC. I skipped over (manually) PRC_ALIGN and went to PREP_PRC_ALIGN and then used PRM to maximize AS_A_DC. For this PRM step was moved mostly in negative-yaw.
- Moved on to SRC Alignment, but I was using INIT_ALIGN node for this alignment and during this step saw that guardian was going through PRC Align (!)---so I went DOWN and then finished off the alignment with ALIGN_IFO only.
- Oh and another note is that the Green-Y-Arm needed to go through a Scan Alignment twice to get flashes of 1.0 to lock (flashes at 0.9 was not to lock after 1st Scan Alignment)
- Then took H1 to PREP ASC for commissioners to touch up alignment there. (H1 was able to get there with no issues)
- 1620 Equipment clean up from EX (mitch.randy)
- 1640-1655 blue articulating lift begins trip from EX to Corner (mitch)
- orange lift will be picked up by rental company next week
- 1707-1720 small green tractor making EX-Corner trip (randy)
- 1859 GRB short
- 1927 Connection issues started to be observed (Ops Teamspeak connection lost, DARM FOM had error regarding kerberos ticket, & phones went down). Notified Erik & Dave for recovery.
- 2249-2315 Checking out CO2 laser in Optics Lab (matt T., julia R., caroline C.)
Manual Align notes with PRC Notes:
- ISC LOCK to Manual Alignment
-
Take both ALSx +y nodes to Initial Align Offloaded
- Align IFO to Input Align Offloaded
- PRC Align Has issues with WFS, so we want to avoid PRC WFS steps
-
Align IFO--> MIch Bright Offloaded (can I go directly there, I think it goes to DOWN on its own)
- Align IFO --> SRC Align Offloaded
- Then DOWN and go to ISC LOCK
