Revision as of 01:45, 16 July 2013
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.
turn on vega camera and check interfermetence.
measure flux and xchan ratios for each beam with WL source.
> mirc and champ (?)
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
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
