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

Osamu and Kiwamu received 40m safety training on Thursday, Feb 19, 2009

The 40m lab specific safety training is done. The participants were

Stephanie Erickson, Clara Bennett, Chris Zimmerman, Zach Commings, Michelle Stephen surfs and Drew Cappel  postock.

They have already went through the Caltech Safety Office laser and general safety training.

They still have to read, understand and sign the the SOP for the laser & lab

Kevin Vigue, our high school summer student went through the 40m specific safety traning yesterday.

 You said that the use of FAXST was forbidden for phds and graduate students. I had to swear on the promise of not ever buying an other FAXST

We lost our key to the Lightwave 125/6-OPN-PS   The key shop just made one look a like that works.

The 40m safety audit will be at Wednesday afternoon, March 3

Please participate getting our lab to inspection grade safety level.

The 40m's new undergrad Kevin Kuns was introduced to 40m safety hazards. He is new and needs guidance as specially with 2W laser work.

Peter King will train him on Friday to LIGO-laser standard.

I borrowed the Olympus and forgot to leave a note - I should have it for at most a day. dmassey@ligo if you need it urgently

Larry stopped by today and had to disconnect the m25 machine (this is the 1st GC machine on the left as you walk into the control room) because its IP was conflicting with a machine over in Downs.  Do not use 131.215.115.125 as the IP on this machine as this is already assigned to someone else.  They couldn't figure out the root password to change it which is why it is not currently plugged into the network, and is not to be until an appropriate IP is assigned.

They've asked that whoever set the machine up to please contact them (extension 2974).

Our visiting graduate student Yuta Michimura received 40m specific basic safety training today.

Our new undergrad Joonho Lee received 40m specific basic safety training yesterday.

Yuta and Joonho are scheduled to participate in the LIGO-laser safety tutelage with Peter K on Oct 12

Yuta, Joonho, and Suresh received the Basic Laser Safety Training from Peter King today.

Now, we got homework.

Our new postdoc Suresh Doravari received 40m specific safety training last week.

Please remember to cover the optical tables !

40m wiki seems to have been down for quite a while now but I can't see any info in the elog about it.  Is there some ongoing problem?

 There was an email from Dave Barker about this.  They had to reorganize the DNS at LHO.  The URL that should be used is: http://blue.ligo-wa.caltech.edu:8000/40m

 Nope.  I know I had the right address, and it was down for me too all weekend.  It's better now though.  blue.ligo-wa.caltech.edu was up though.

 Thanks Jamie, I've updated the links from the ATF wiki to reflect this.

Whenever you modify any of the front-end code in /opt/rtds/caltech/c1/userapps, such as models, scripts or medm screens, REMEMBER TO COMMIT YOUR CHANGES, WITH A LOG MESSAGE!!!

cd /opt/rtcds/caltech/c1/userapps/trunk
svn commit path/to/modified/file

If you forget to commit things, they may be purged and you will loose your work.  ALWAYS COMMIT!

Things to note and watch out for:

• When you commit, make sure you specify explicitly the path to the file that you are committing.  This repository is shared by all LIGO sites, including the sites (LHO and LLO) so you really want to make sure you're not committing anything that affects anything other than "c1" (ie. the 40m)
• Only commit one file at a time, unless the changes to multiple files are tightly coupled.
• Never commit without specifying the path to the file that you are committing.  Other people may be working on other files in the repository, and you don't want to commit their work with yours.
• YOU MUST LEAVE A LOG MESSAGE.  Your log message should be specific to the file you have modified, and should be clear and verbose to explain exactly what you have done.
• Use the "svn status" command to give you an overview of what is going on in the working directory.  This will tell you which files have been modified.  See "svn help status" for more information.

If you have questions ASK.  Don't force things.

Also, remember to update the svn working copy before you begin doing any work, to make sure you're working on the most recent version:

cd /opt/rtcds/caltech/c1/userapps/trunk
svn update

The manual instructions on the 40m wiki for restarting wouldn't work.  I killed the process okay, but then I got an error saying it "couldn't bind to port 8080, please try again using -p to select port".  The automated script worked though.

Mess in the lab is increasing. Kiwamu and I had to clean up some stuffs to continue our work.
(i.e. some components were disturbing to open the lid of the tables.)

Basically the tools/equipments/component/cables/digital cameras/lens caps/IR viewers
you have used for the day should be cleaned up at the end of the day.

If one likes to leave a temporary stuff, leave a note to indicate by whom, for what, how long
it will be kept like that, and when one is going to back there with contact info like the cell phone #.

Elog went nonreponsive. SSH'ed into nodus to run restart script. Elog came back ~15 minutes later.

JA - MIE - RO!

Bob, Callum and Daphen noted that our keeping a JDSU HeNe (max power <4mW) is against somebody's SOP.  So I cleared everything that relates to 40m SOS suspending to the bottom shelf of the 2nd cabinet in the cleanroom (the back set of cabinets nearest the flow benches).  The door has a nifty label.  Things that are in there include:

HeNe

HeNe mount

QPD and micrometer mount

microscope and micrometer mount

iris

Al beam block

Magnet gluing fixture

dumbbell gluing fixture

The electronics that we use (HeNe's power supply, 'scope, QPD readout) are still on the roll-y thing under the flow bench.

 [Koji, Suresh]

  We tried to locate the sixteen analog output channels we need to control the four tip-tilts (four coils on each).  We have only 8 available channels on the C1SUS machine. 

  So we will have to plug-in a new DAC output card on one of the machines and it would be logical to do that on the C1IOO machine as the active tip-tilts are conceptually part of the IOO sub-system.   We have to procure this card if we do not already have it.  We have to make an interface between this card output and a front panel on the 1X2 rack.  We may have to move some of the sub-racks on the 1X2 rack to accommodate this front panel.

  We checked out the availability of cards (De-whitening, Anti-imaging, SOS coil drivers)  yesterday.  In summary: we have all the cards we need (and some spares too).  As the De-whitening and Anti-imaging cards each have 8 channels, we need only two of each to address the sixteen channels.  And we need four of the SOS coil drivers, one for each tip-tilt.  There are 9 slots available on the C1IOO satellite expansion chassis (1X1 rack), where these eight cards could be accommodated.

  There are two 25 pin feed-thoughs, where the PZT drive signals currently enter the BS chamber.  We will have to route the SOS coil driver outputs to these two feed-throughs. 

   Inside the BS chamber, there are cables which carry the PZT signals from the chamber wall to the the table top, where they are anchored to a post (L- bracket).  We need a 25-pin-to-25-pin cable (~2m length) to go from the post to the tip-tilt (one for each tip-tilt).  And then, of course, we need quadrapus cables (requested from Rich) which fit inside each tip-tilt to go to the BOSEMs.

   I am summarising it all here to give an overview of the work involved.

Koji, Jamie and I talked together and I decided to VENT TOMORROW MORNING. Main purpose of this vent is to see if PRM is flipped or not.

Vent schedule:
June 28 (Thu)
  Prepare for the vent tonight

June 29 (Fri)
  Start vent in the morning
  Look into PRC in the evening. If PRM was flipped, we will correct them. We'll use REFL to align the PRM. If PRM was not flipped, look into PR2,PR3 and other related optics.

June 30 (Sat)
July 1 (Sun)
  Thinking time. I can work if needed.

July 2 (Mon)
  If we need something else to do, do it.
  If not, start pumping.
  July 4th is the Independence Day. So, I need IFO working before July 4th.

Check List:
 We will just open the BS chamber.
  - PRM flipping
  - PR2, PR3 flipping
  - PRC suspensions
  - Cipping check in PRC

 What do you mean by PR2, PR3 flipping?  They are (supposed to be) flat mirrors, so obviously they should be installed correctly, but they won't change the mode matching in a huge way if they're backwards, right?

For the PRM, I recommend checking (a) the arrow inscribed on the thinner side of the optic and (b) that the arrow *actually* points to the HR side.  I'm pretty sure I installed all the optics with the arrow pointing away from the OSEMs, but I never did a thorough check that the arrow always actually pointed to the HR coated side.  I don't remember any optics where I said "hmmm, that's funny, the arrow is pointing backwards", but nor did I write down that I had checked.

Also, hopefully the PRM is correct.  If however it's not, that means that all of the magnets are glued onto the HR side, and we'll have to redo all of the magnet gluing.  The guiderods should be fine, but all 6 magnets would need redoing.  If we were very, very careful and didn't break any of the magnets off of the dumbbells, it's a 24 hour turnaround due to drying time.  Since inevitably we break magnets away from dumbbells, conservatively we should think about a 48 hour turnaround. 

We see some ghost beam spots at POP. This may come from the back of PR2 and PR3. Also, they may change mode matching because of thermal lensing, mirror deformation, and other unexpected reasons. I thought we should check every mirrors in PRC, if PRM is not flipped.

We are going to check PRM just because we spent so much time for the PRC problem, and still don't have the solution or evidence.
PRM flipping is kind of the only idea for the root of all evil -- terrible beam shape, low PR gain, unstable PRMI lock.
So, I want to check with my eye during the stay.

I don't think we have to redo magnet gluing. It's okay to leave them on HR side.

Issues in PRC:
  1. Power recycling gain is too low (~ 15 instead of 40, according to Kiwamu).
  2. Mode matching to both arms are ~90%(see #6859), but PRC has terrible mode.
       Clipping/flipping in PRC?
  3. From cameras, beam spot moves so much when PRMI is locked.
       Alignment? Mirrors(especially PR2/3) moves too much?
  4. Error signals are glitchy when PRMI is locked.
       Servo design? Mirrors moves too much?

What we have learned from the vent:
  1. PRM, PR2, PR3 was not flipped.
  2. Their suspensions looked OK, too.
  3. We noticed clipping at BS and Faraday. They must be avoided when tip-tilts are installed on next vent.

  4. Took useful photos for next vent. Positions of green optics on optical layout CAD must be updated.
  5. It is not so difficult to recover the IFO state after cycling the vacuum if we use attenuator setup using PBS (see elog #6892).  But, of course, we need plans before cycling.

Commissioning Plan:
  - measure PRMI power recycling gain from POP
  - FPMI using ALS
  - measure PRFPMI power recycling gain from TRY/X
  - correlation between beam spot motion at POP camera and glitch
  - correlation between PR2/PR3 motion and glitch (how can we measure PR2/3 motion? set up oplevs?)
  - mode scan for PRC, using AS AUX laser
  - beam profile measurement at REFL,POP
  - refine servo design of MICH and PRCL

These are all priority action items need to be done before I come back (in mid-September).

In light of the Yend auxiliary laser's ill health, I think we should reconsider the possibility of changing out the Yend laser table next week.

My thinking here is that if whatever the new mode matching solution is for a replacement laser (Tara has borrowed our spare NPRO that used to sit on top of the fridge, or we could take Annalisa's) requires a rework of the table layout, we might as well put the new layout onto the new table.  So, we need to figure out what laser we will put in as the new Ygreen, and what it's waist looks like.  If it just requires a small movement of existing lenses or new lenses in similar positions to the current ones, we can keep living with our current table.  But, if the mode matching solution requires enough changes to distances / lens placement / whatever, we should think seriously about putting in the new table next week.

Here's what I would like to see happen on / before Monday:

Annalisa - Mode matching solution for new laser.  If we get the laser back from Tara, this will involve first measuring the waist, otherwise we already know the waist of the ABSL laser that Annalisa is currently using.

Annalisa and Steve - Find optics for new mode matching in the lab, or order them by Monday afternoon.

Manasa - List of every screw, washer, optic, mount, etc. that will go on the new Y end table, with a notation as to whether or not we have it in-hand, and if not, what needs to happen before we do.  Also, for things that we don't have, I'd like to see a summary of temporary solutions (e.g. keep using current mount for doubling crystal while new one is being machined).

Manasa / Annalisa / Koji - will the new mode matching solution fit within the existing layout, or do we need to redo the table layout?

Zach has just replied, and said that we should feel free to take the laser from his iodine setup in the West Bridge subbasement, in the ATF lab. 

Annalisa, please ask Koji or Tara to show you where it is, and help you bring it to the 40m.  You should install it (temporarily) on the PSL table, measure the waist, and find the beat in IR.  Elog 3755 and elog 3759 have some of the details on how it has been done in the past.

 Ok, I'm going to contact Koji.
