- Problem with AO electroniccs: power supply for grabber CCD47 seems to be dead

Details

All times are UT
Files are luci2.20150325.NNNN.fits

- N30 T_Cam=73.5K
#0001 neglim, #0002 middle, #0003 poslim (best)

- Pupil alignment
#0004 FM1 M1: (y) 0steps M2 (x) -3000steps
-3000 only necessary to center in most illuminated area, otherwise NO movement necessary
FM4 to re-center field: M1 -250steps M2 +1600steps
#0006 N30 after re-align @ poslim

- Scale N30
from #0006 15.00 milli-arcsec/pix +-0.01, N = 30.0

- Input AO: N3.75 center = 1037 / 1057

- Preparation
init hexapod & center ARGOS cal unit in N375 FoV
focus before (January 2015: 52.8mm) now ~55mm
#0008 N30 FeII /cl subwindow 0.17s
-> image looks VERY similar to that in January!

- Shift & add cube images & automatics NCPA scan

Failure: power supply for grabber CCD47 dead (?)

-> no more working
