2013July JDM Observing Logs

Top-Level Goals

• Install new wolverine2

• fix mirc spooler bugs that cause loss of ople communication

Punch List

lab --- do super careful alignment of pzt feed on worst beam

check for pzt distortion using engineering beam on all beams

try to improve grounding on mirc?

• go rid of many peaks by moving mirc ground from the overhead pipe to the champ enclosure which is isolated by 3 chokes. maybe we need more chokes.

*no luck.  moving round actually did nothing the next day.. so probably just time variability.

turn on vega camera and check interfermetence.

• did not cause spikes.

measure flux and xchan ratios for each beam with WL source.

> mirc and champ (?)
> see notes below.

check tiptlit centers.

clean up wolverine python.

• unify mirc branches fb thinks python2.7 code will run fine.
• cleanup so we have a porpoer svn checkout version running under wolverine /devl and observe is linking to the /devel files.
• same for champ

Bug/Wish List

• default values of shuttermatrix

• get telescope beram order from chara shomehow for mirc and champ, including new buttons on guis.

• proper slts/prsm labels in fiberexplorer

• fix defaults (ftgui, mric shutter matrix)

• mirc: save xy and Z of fiber positions

• save POPS in mirc header

• mirkwood server should start w/0 vme on

• mirkwood spooler should run w/o all servers up (opler/tiptilt, etc)

• (recent) Delay line positions

• FIXED fix zeros in uv coordinates FIXED!!

• send ople a target time instead of 0 0 0 0 0 0 (not needed.. just use the HA which is returned)....

• mirc and champ: replace pulldown menus and text boxes with other elements.

• champ: ability to algin in wide field mode.

• champ. fix stop exposure crap (hard)

• champ. save syncronized spooler data even for large strokes

• champ. test phase tracking mode

• champ filter SPIKES out of amplitude(t) gui plots

• make sure search to semi-lock can catch spikes of good seeing (lucky fringes) but

not get screwed up by huge spikes caused by electronics. currently it seems the system misses real fringes probably due to spike suppression algorithm being too primitive.

• improve usability of champ gui. the top part of the gui should not be so sluggish. only the plots need to have a timer, no the other widgets.

• fringe 6 B5/B6 pull down state stays in search , doesn't go to semi-lock visually

• whens aving data, the amp[opd] of first BC is corrupted but seems to not affect tracking.

• change colors of AMP(OPD) from red/blue to something that doesn't appear match the flux(OPD) graphs

• champ. add more readout modes.. shorter than 30micron stroke, slower than 250 hz. we need a 'phase trakcing' mode this probably like 20 microns.

Theo Questions

• client read socket in socket.c .. shouldn't there be sleep in this loop?

• we use sockman for ople but get same port number to use. normal?

Progress

• FB found problem with memory alloc in spooler. yay!

2013 Jul 15

4pm. JDM

doing lab alignment of champ using engineering beams

starting with 1. will note the MIRC fluxes and CHAMP fluxes.

4:10pm. ENG BEAM 1 in line. WAY OFF on CHAMP TABLE !!

beam1 w1

aligning MIRC and CHAMP to get flux levels.

MIRC BEAM 1. QUAD 262cts XCHAN (pix202): 35 FWHM 7.1 7.1 (using 3mu step)

4:25pm

ALIGNgui CHAMP (250Hz, 50mu):

""CHAMP BEAM 1: ""

• great image quality on b1l1. 220cts.
• decent image b1r2. 110cts

discovered R1/r2 mount was not seating properly.. explaining th eextra wobble we noticed.. ugh. this explains a lot !!

REALIGNED BEAM 1 using ENG BEAM:

• great image quality on b1l1. 220cts.
• decent image b1r2. 110cts

5:08pm going on to beam2 (s2)

• MIRC beam2: quad 232cts. xchan 28cts (pix215) FWHM 7.1 /8.1 mu (using 3mu step)

""pre-alignment""

• CHAMP beam is clearly off the R1 target (before re-alignment)
• ok image quality. not best. B2 L2 90cts
• a bit worse image quality B2R3. 70 cts.
• bc image hard to find. image elongated a bit. B2R2 80 cts

5:19pm going in lab to align. (done at 5:33p)

""after alignment in lab using eng beam"

there is some vignetting (maybe 10%) on the PZT. Also, perhaps slight defocus due to mounting of PZT mirror. need to loosen screws and NEED TO REALIGN THIS SUBSYSTEM.

• B2R2 100 cts.
• B2R3 70 cts
• B2R2 (it took me forever to find this...but was ok in the end). 85 cts

not so much better overall !! strange.

6:05pm going to beam 3(s1)

• MIRC beam 3: quad 245cts. xchan 21 (pix 221) FWHM. 7.6 / 7.3mu (using 3mu step)

""pre-alignment""

• CHAMP beam. B3L3: 125 cts image circular
• CHAMP beam B3R4 160 cts
• CHAMP beam R3R3 120cts

""no time for re-alignment" seems ok.

we see this funny oscillation

""BEAM 4""

• Mirc Beam 4: quad 191cts (low compared to others are 240). xchan 19ct (pix166) FWHM 7.7, 8.8mu (seems lsightly out of focus at 8335)

• trying focus 8345. slightly better. 193cts (same), FWHM 7.1,8.1 mu

• CHAMP:
• B4L4 145ct (nice image!)

• B5R6 130cts
• B5R5 140 cts

• nice !!

• B6L1 40 cts.

""SHOULD continue alignment game for beam 3-6"

2013Jul17 lab notes

BEAM 2 looked bad on CHAMP last night.

• a) I set up visbeams and checked alignment carefully all the way for B1,B2, B5,B6
• b) for B2 I checked carefully that the retro in place works well compared to actually adjustable large retro. no change in

tiptilt center either.

• c) I took pictures of the tip tilt offsets. actualy B6 was worse. about 3/5 or so away from center. I'm asking judit if problem.
• d) check on CHAMP table.

not perfect... but B5 is not so different off then B2.. so not clear.

• f) check shear going out through DL and beam compressor by looking at M10 target and moving Delaly the full length. the image should not move.

I will do this tongith

• is there something funny about aligning on laser on champ? due to visible light not traversing the same ir apth, eg. wedge on dicroics?

the coude alignment was tweaked up, so maybe things will be better.
