The fire alarm test was completed at 13:30 yesterday.
I updated the 40M Emergency Calling List by replacing Rob by Yoichy. The calling order: Vass, Aso and Taylor.
Rana and Yoichy were added to the "Registered PSL Operator List" and posted it in the lab. (not in the document, that should be up dated)
We are getting ready for the annual safety audit. It will be held next week at 14:00 Friday, Feb 13, 2009
Please participate in the preparation by correcting it or just tell me.
Rod Luna is organizing the pick up of the following old equipment:
HP laser jet 5000n, 3 of 19" 10 base-T network ports and 4 small hubs,
2 Sun monitors, 1 Viewsonic monitor, 7 keypads and
Hitachi scopes 2 of V-355, 2 of V-422, 1 of V-202 and 1 of V-6165
MOPAs and their settings, powers of 7 years in the 40m
I have been getting ready for the annual safety inspection in the past 2-3 days.
Osamu and Kiwamu received 40m safety training on Thursday, Feb 19, 2009
The spare M126N-1064-700, sn 5519 of Dec 2006 rebuilt NPRO's power output
measured 750mW at DC2.06A with Ohpir meter.
Alberto's controller unit 125/126-OPN-PS, sn516m was disconnected from lenght measurment NPRO on the AP table.
5519 NPRO was clamp to the optical table without heatsink and it was on for 15 minutes.
The outside particle counts for 0.5 micron are 3 million this morning at 9am. Low clouds, foggy condition with low inversion layer.
This makes the 40m lab 30-50K
I just turned on the HEPA filter at the PSL enclosure.
Please, leave it on high
CES Mezzanine is beeing rebuilt to accommodate our new neighbor: the 20ft high water slide...& .jacuzzi
All our ac power transformers are up there. Yesterday we labelled the power switch of 480VAC on the mezz
that we need to keep to run the 3 cranes in the lab.
SRM, ITMX, ETMX, ITMY and ETMY lost damping at 4:55am this morning from 4.8 magnitude earthquake.
Their damping were restored.
C1:SUS-ITMX_URSEN_OUTPUT swich was found in off position. It was turned on.
MZehnder and MC were locked.
The WFS qpd spot needs recentering
SUS-MC1_SENSOR_SIDE and SUS-MC2_SENSOR_UL are glitching
Yesterday's 4.8mag earthquake at Salton Sea is shown on Channel 1
ETMY sus damping was found to be tripped.
It was retored.
All fluorecent light were turned off. Please try to conserve some energy.
Eric Gustafson is handling the old HP4291A rehabilitation. Tarac picked both units up today.
March of 2008 Tucker Electronics failed to fix it's intermittent ~25MHz 0.5V oscillation at the swept sine output

The Caltech gasoline storage tank is being upgraded.
They are jack hammering and digging with bulldozer 50 yards south of ETMY
Thanks to Joe B who made the SRS RGA working with linux
Last data file logged at 2008 Oct 24 with old Dycor unit
First data file logged at 2009 Feb 10 with SRS
Rga scan of day 231 since pumpdown pd66-m-d231
m stands for maglev pumping speed, vacuum normal condition of valves,
cc4 cold cathode gauge at the rga location,
cc1 is real ifo pressure from the 24" tube at the pumpspool,
PEM-count temp: vac envelope temp at the top of IOO chamber
Vacuum normal valve condition was changed to accommodate SRS-RGA calibration.
VM1 was closed to isolate the RGA from the IFO.
Cold cathode gauge CC4 is reading normal.
CC1 is glitching, it is probably dirty.
CC2 is fluctuating too much and it is cutting out for 6-7 minutes. It must be insulated by deposits and there is no emission current.
I think the same goes for P1
They will have to be replaced at the next vent
Vacuum valve configuration is back to VACUUM NORMAL condition. RGA calibration completed.
RGA scan attached is the backgroud of the rga with std cal leak open, sn 08581
Krypton at amu 84 and Argon at amu 40 are the cal signals.
Our Osaka TG360MB maglev failed with CSB error message. This means that the dry emergency landing bearing has to be replaced.
I will consalt with Osaka about the choice of replacing bearing or installing new spare tomorrow.
Mean while V1 is closed and the vac envelope is not pumped.
Valve configuration: BG -background, pumping on the RGA-only
High voltage to IOO PZT steering mirrors and OMC are turned off.
PSL output shutter is closed and manual block is in place.
I will start cooling the CYO pump in the morning, so the IFO will be pumped by noon.
Outgassing plus leakrate after 10 hrs the pressure is 2.3 mTorr
This rate of rise is normal and it is safe to work with the ifo.
