One recommendation from the June 6-9 CDS Face-2-Face meeting was that the teststands need their own alog as work get geared up for post-O2 upgrades. Keith and Dwayne have created the new alog at LLO:

Test Stand ALOG

You should not see any more X1 alogs in this alog from now onwards.

The optical timing distribution system in the staging building is no longer in sync with the master timing in the MSR.  Because of this, the GPS time of the models running on the test stands is off by a second or two.  This should be fixed at some point when it is convenient to shut down the models and troubleshoot the system.  Until then, the system should work so this repair is not urgent.

This affects both seismic and suspension test stands in the staging building.

I have restarted the DTS, triple test stand, quad test stand, and seismic test stand.  The test stands in the staging building have only the IOP model and daqd processes running, so the users will need to start the appropriate models for their tests.

Remove oldest frame files from tripleteststand and seiteststand2 to reduce file system usage to safe level. (general maintenance)

The GDS software (diaggui, awggui, foton, ezca*, etc) has been updated on the suspension and seismic test stands to include modifications for the June 30 leap second.  Also, the diaggui and awggui channel selection menus have changed to include 6 levels of hierarchy in the channel selection.  This should make selecting channels easier as the very long menu with the tiny scroll bar has been replaced with hierarchy.

Manually removed oldest frame files to reduce /frames disk usage on tripleteststand, bscteststand2, and seiteststand2. (Routine maintenance)

Both X1 test stand computers have been restarted in the staging building following a timing system interruption to move AC power for the timing master.  All previously running models have been restarted.

Due to a timing system interruption at the master fanout, the suspension and seismic test stands needed to be restarted.  Models were restarted, but no BURT restore was performed.

Just to give an update on the Staging Bldg Cleanroom issues noted last month.  Last week, the flimsy castors (actually, it was just poorly designed cleanrooms---weak castors not installed securely in thin boxbeam legs) were replaced with much beefier replacements (after seeing cross-section of legs, still wish they were thicker/stronger like the VEA cleanrooms).  Photos are attached.  These were replaced on the two (of four) cleanrooms we move the most down there.

(obviously both of the attached photos should be rotated clockwise 90deg, seems like the alog doesn't like my photos!)

The suspension and seismic test stands have been started after the power failure of this morning.

Tuesday Jan 10 between 17:45 and 18:30 PST, bscsteststand2 and seiteststand2 in the staging building were rebooted and the models that had been running were restarted to correct timing.  This was done as a result of moving equipment that supply timing in the MSR, which interrupted the 1PPS timing to the staging building.  The timing signal is now supplied directly from the master fan out in the MSR.
