Grouting of the remainder of the HEPI piers, transmitter and receiver pylons in the LVEA began on Monday morning by Reiboldt and Associates. The grouting has consumed more product than was originally expected and we have used up all that we had. I have ordered more grout and that should be onsite today, meanwhile, the grout crew will be out today. Progress to date includes, all of the HEPI piers on HAM 5 & 6, the large carbon fiber leaner on the south side of HAM 4, and the large stainless steel leaner pylon on X-Arm. Remaining items to grout in the LVEA include, 5 of the small transmitter pylons, and 1 each of the large carbon fiber and stainless steel leaner pylon. The plan is to finish these items in the LVEA tomorrow and move to the End stations afterwards.

Yesterday afternoon I began the disassembly of Supply Fan 5 to investigate a very noisy bearing. I informed the control room that I was going to increase the flow on SF-6 from ~6200 CFM to ~ 8500 CFM to compensate for the reduced air flow of one fan being down. I will continue with disassembly today and if all parts are readily available, I hope to have the fan back up and running by the end of this week.
John, Chandra We isolated the beam manifold from QDP80 and are now backing turbo with scroll only. Control cable switched to scroll box. Safety valve set point on both X and Y pump stations is 5e-2 Torr. X: 5.94e-7 Torr Y: 1.82e-6 Torr
John, Chandra Started turbo on Y beam manifold with inlet pressure at 1 Torr and pump water cooling ON. X: 8.0e-7 Torr Y: 4.9e-1 Torr
John, Gerardo, Chandra Yesterday Kyle and Gerardo noticed the current on annulus IP on GV-5 was high (off scale). Today we noticed it was at 2 mA. We tapped on the vacuum piping around the pump and the current rose. Then we opened the valve to the annulus of GV-5's gate. The current rose to 6 mA and then quickly fell to 2 mA. Closed valve again to isolate GV-5 gate annulus. Now the IP is reading 1 mA.

John, Chandra Now backing turbo pump on Xarm spool with scroll pump. Closed QDP80 valve on Xarm spool pump station. Closed vent/purge valves at both X & Y spools. Closed valves on Inficon gauges (PT-170 and PT-180). Pressure on PT-170 reading 1.56e-6 Torr.

The TCS SIM model has been updated. Further details soon, but now there are calibrated channels for the arm powers. The values are in Watts. The names are:
H1:TCS-SIM_XARM_POWER
H1:TCS-SIM_YARM_POWER

Other than knuckle bustin head bangin pain, not too bad a job. Did find the data connector for the '3rd' corner satellite box seemed extra loose on HAM3. It has a gender changer as well so there was a lot of strain & wobble present. Fil saw that there was no fasteners tying the header to the board so it was just held with the pins and solder. He managed to get some screws in without too much disassembly--certainly better now. Say a hail-mary against 0.6hz.
1/2 open LLCV bypass valve, and the exhaust bypass valve fully open.
Flow was noted after 2 minutes, closed LLCV valve, and 3 minutes later the exhaust bypass valve was closed.
Next over-fill on Thursday, March 17th before 23:00 utc.

We transitioned to Turbo pump on the X Beam Manifold at 15:00 local time.Pressure is currently 3 e-1 torr.
The Y Beam Manifold is currently at ~5 torr.
On the vacuum overview medm I have replace the PT170 and PT180 gauge pairs with the new Beckhoff gauge. The Beckhoff IOC was running the TORR records with zero precision, so I have manually set the PREC field to 2 for these (using caput, we need to make this permanant).
FAMIS #4666
Attached are 7 day pitch, yaw, and sum trends for all active H1 optical levers.
After Richard, Fil and Patrick got the new PT170 and TP180 Beckhoff gauges being read out by ECATC1PLC1, I elected to add these channels to the H0EDCU_VE.ini DAQ file after we encoutered problems getting the full ecat ini file transfered to the userapps area. The additional lines are shown below.
Hugh and I had performed a "make install-h1isiitmy" earlier in the afternoon, so this DAQ restart required us to restart the H1ISIITMY model. We confirmed with Hugh and made the model restart just prior to the DAQ restart.
The DAQ was restarted at approx 6pm PDT Monday, The TORR channels are trending correctly. I modified the vacuum overview MEDM screen to display the TORR channels.
This morning we copied the new h1ecatc1plc1 autoBurt.req file into the ecat target.

Replaced the keyswitch on the TCS Laser Controller Chassis. Old keyswitch allowed user to remove key in both on and off position. New switch does not allow key to be removed when CO2 laser is on.
Placed a DC power breaker switch in-line with the TCS ISS Interface chassis (Bug 668) on TCSY and TCSX.
Added 125ml water to the X-chiller. Removed the lower side panel to get a good view of the diode chiller reservoir. Added 2000ml water to the diode chiller. I have replaced the side panel.

Yesterday (Monday 14th March) we moved most of the NFS exported files from h1boot onto a new server called h1fs0. This move was more invasive than last week's /ligo file system move as all front ends and DAQ computers were impacted.
The process was:
The DAQ restart was messy. We saw the two framebuilders report different data CRC which we had not seen before. Also h1fw1 restarted with apparent slow file access for some time and then the problem apparently went away. We are monitoring this.
Today we are catching those machines which were overlooked yesterday.
For systems which only mounted /opt/rtcds from h1boot, I have a script to convert them to mount from h1fs0:
#!/bin/bash
# make changes to move the h1boot mounts to h1fs0
# in /etc/fstab, replace mount command with sed
cd /etc
cp fstab /tmp/fstab.$(date +%Y%m%d%H%M%S)
cp fstab /tmp/dave.tmp
cat /tmp/dave.tmp|sed 's/h1boot:/h1fs0:/rtopt/g' > fstab
# ensure h1fs0 has entry in /etc/hosts
cd /etc
cp hosts /tmp/hosts.$(date +%Y%m%d%H%M%S)
echo "10.101.0.13 h1fs0" >> /etc/hosts
