(Corey, Greg, Hugh)
In preparation for installing the HEPI Assemblies on an upcoming BSC, Greg & I set the HEPI Foot to it's "nominal position" for four of HEPI Assys (to be installed on BSC7). On the HEPI "Cage", there is a part/serial number marked on the base. The four we worked on were Serial #'s: 54, 77, 51, & 45.
I took (3) plastic containers from the ISC Optics cabinet near the H1 PSL into the Optics Lab (container ISC-18 (various optics), ISC-19 (1" and 2" newport mounts) and unlabelled with bases and posts). We will use these parts to set up the Reference cavity for the H2 One Arm Test (H2OAT). We will keep track on what we took from the containers, to keep the stock list up to date. Also, I took the 'spare' 21.5 MHz modulator from the cabinet from the cabinet labelled 'Camera', which has a list on the door with 'Who' took 'What' and 'Where' with 'Date'. So I listed the modulator and my name on it as well. I guess I will double check if we can use this modulator. Still not sure what the beam height on the table should be, as the RF diode is at ~3" height (unless there is a magic spacer). I guess the 'soon to come laser' will probably set the standard.
I have created a new machine which sends EPICS alarms as text messages to cell phones. It is a GC machine which is also on the iLIGO CDS network. Its names are:
sugarloaf.ligo-wa.caltech.edu cdsalertsIt is running a modified version of the email_alarms.pl script, ported from solaris to linux and using burt in place of caGet. This system can send emails directly, even to Sprint phones. So it is not dependent upon the robinson email proxy which the old system needed.
We completed the Quad 3 rough alignment for both chains. Set up the optical lever and started on the fine alignment. Found the Reaction chain yawed relative to the Main chain and the structure, and adjusted the Top Stage blade angles to remove the yaw. We will work on setting the pitch tomorrow.
~9:45 fb0w was re-booted 10:30 - Rodney to Squeezer area to flush out eyewash station Hugh and others prepping for HEPI install 11:35 – Dave reports that fb0w is stable and rebooted the machine to begin writing frames again. 12:30 – truck for freight pick-up from Doug
Flushed all of the eye wash/shower stations in LVEA, LSB Optics lab and Warehouse
H1 DAQ system.
LDAS were down due to cooling issue in their server room. While the disk system for fb0w's frames were not available, fb0w was ran in partial mode (real time data only). LDAS have recovered their disk system and fb0w is now writing frame files again.
The data gap on nds0 is
08:50 H-R-982947008-32.gwf
11:37 H-R-982957024-32.gwf
For data in this period, please use nds2.
RO unit shut down in auto from level control
The aLOG will be rebooted tomorrow after some routine system maintenance. The reboot should happen at 10am Pacific time 1 Mar 2011. Please save any entries you may be working on before that time. The down time is expected to be a minute or two.
Started RO unit this morning at 06:45
The chiller was running Friday and Saturday morning for the Corner station. We lost the chiller some time on Saturday, but the CWP remained running at 45 Hertz, but there was no display on the controller panel. I've turned off that pump, manually restarted CWP2 and Chiller 2 started. Once temps return to normal we will turn the heat back on.
Due to a loss of communications to the chiller yard we have no chilled water to serve the LVEA and OSB. Temperatures were starting to climb so I have de-energized two heater circuits for the LVEA.
I have now turned off all heat in the LVEA and OSB.
Thawed out CP1 and CP2 actuators am leaving shop lights on to keep them warm overnight
9:00 work begins cleaning and prepping for IO tube removal 9:00 – Jodi and crew beginning brush test and sampling in the test box by ~1:00 - work resumes on the IO tube removal ~1:30pm - PAP tour comes to the control room ~2:30pm – tour group with Dale to the control room ~3:45pm – work completed on removal of IO tube.
