Restarted the daqd process on h1broadcast0.  Prior to doing this, David Barker revised it's broadcaster.ini file to specify the list of channels requested by John Zweizig, and modified the daqdrc file to cause the daqd process to read the broadcaster.ini file.

The date on the h1broadcast0 machine is Jan. 1, although the time of day is correct.  This will be corrected.

Yesterday, the two remaining spool pieces were moved into the cleanroom. One spool was attached to BSC9 and a second spool added to fill in the gap between BSC9 and BSC5. Since BSC5 already had a spool piece attached, it was possible to marry the three spool pieces and complete the beam tube between the chambers.

Yesterday, the C-3 soft roof was pulled from HAM3 and installed on the cleanroom over HAM6. 

Sloooowww vent is done -> As such, I connected the HAM6 vent/purge connection and cracked it open -> Now the YBM vent/purge is connected with its valve partially open and the HAM6 vent/purge is connected with its valve partially open -> Purge-air air currents across the ITM (real or imagined) can thus be manipulated to compensate for the 1st component to be removed (YBM spool, or HAM6 door)

The non-functioning Horizontal L4-C L41659 on Pier2(SW) was replaced with L41366.  While at it I 'leveled' the L4-C based on its clamping bracket D030586 but other data suggest that may only possibly help.  This required about 0.09" of shim although this isn't the amount of out-of-level due to geometry.
I've left the HEPI system on WHAM3 unlocked; I want to see if there is any slow creep of the system while free.  I'll lock it up in the morning and then summarize the numbers--yes there were some shifts from locked HEPI to unlocked position.

As of 4:00 PM local today, the vacuum level at BSC 8 = 720 torr and at BSC 2 = 660 torr.  Richard replaced the power supply for the LVEA test stand sus IO chassis and Jim did some reboots to restore the system, which appears to be running satisfactorily.  Flooring installation is underway at EY.  Seismic's replacement of the HAM3 HEPI L4C appears to have worked.  Michael R and Kiwamu worked on PSL RF during the day.  Apparently tumbleweed baling has continued throughout the day.  Work permits signed by ops today:  3625 (Hugh, HEPI L4C), 3626 (Thomas Vo, oplev removal), 3627 (Filiberto, HAM1/HAM2 cable re-routing), 3628 (Apollo, EY crane support of clean room during flooring installation).

Taking TFs on MC2 from 12:45 pm.

I let Michael R know that the NPRO is off.  H1:PSL_AMP_ENABLEPWRDOG was alarming this morning.

This is just a record for those who care about the slow machine h1ecatc1.
I was playing with h1ecatc1 this evening around 18:10. I got an error message when I tried logging in PLC2. The message said 'Page Fault. PLC is stopped.' Obviously PLC2 wasn't running, so I recovered it by clicking the 'reset' button in the 'online' tab and then clicking the 'run' button. It seems running OK right now.

I ran a quick test today on IM3, which now has the largest offsets of the 4 HAM AUXs.  In the attached plot, red shows the pitch offset, black the yaw offset - blue shows very different behavior when each offset it removed - the damping of the oscillation when the pitch offset is removed shows the optic is touching an EQ stop.

I left all HAM AUXs, IM1, IM2, IM3, and IM4, undamped overnight.

Morning status: Alarms:
Dust, LVEA 2, 13, and EY 1 invalid - I reset the ignore on all 3, since no dust monitors are connected
IOP SUS watchdog, ITMY - OSEM4 yellow
PSL, laser OSC_XchilAlarm, ENV, TEMP_Humidity - cleared up

Activities:
- Table optics install at input arm
- BSC2 transfer functions
- In-chamber cleaning at EX
- Tumbleweed cleanup
- Praxair delivery, 10:04, CP-4
- Vent of BSC1/2/3 and HAM4/5/6
- Optics tables moved into squeezer area in LVEA
- Test stand computer issues

Wired up the WHAM2 HEPI IPS(Inductive Position Sensors) and the Horizontal L4-Cs (Seismometers).  The L4-Cs appear functional as do the IPS.  I zero'd the IPS and removed the Dial Indicators.  The numbers on the DIs would 'indicate' that they have been disturbed beyond usefulness.  While some of the IPS had several 1000 counts, none appeared too close to require position adjustment.  I zero'd the IPS to less than 50counts at the INMON(e.g. H1:HPI-HAM2_IPSINF_H4_INMON.)  The calibration after the ADC is 655cts/.001" so these are very zero especially wrt initial alignment.

HEPI remains locked at HAM2.

Extra slow at request of others -> hope to minimize moving particulate 

1600 hrs. local 

2.1 x 10-6 torr @ turbo inlet -> Foreline @ 3.7 x 10-3 torr 

NOTE: temporary pump system used for this pump-down is ~1/4 the pump speed of the nominal MTP

*Venting adjacent volume today (BSC2....etc) did not communicate to gauge on HAM3, HAM3 annulus is vented* 

It appears the I/O Chassis for the h1susbstst computer (in the LVEA) has died.  I can not get it to power up, after disconnecting the power cord and reconnecting, turning on the power switch results in a momentary flash of LED's, then everything remains dark.

Timing went bad on IOP model running on h1sush2b computer about 10:48 PST this morning.  Restarted h1susim and h1iopsush2b models to reset timing.  Checked with the usual suspects, but no one claims credit for this event.

The baling crew worked on clearing a second lane from the mid-station to the end. The road to the end is passable and both mid and end nitrogen storage tanks are accessible, with turn-around space for trucks. 

Bubba and I checked on the status of preparations for the vinyl installer, who is due on-site tomorrow. The floor in front of BSC6 is clear and ready.
