NIKA2 Re-Commissioning (4th. attempt)
NIKA2 run 75, Cryo run 87
Oct. 13, 2025
14:00-17:00; Martino, Alessandro, Dave, Angel: a new sweep was performed. Previous initialization file: run87_old.ini. Bad/total KIDs counts (cryo window closed) after sweep (Ar1, Ar2, Ar3): 9/1000, 8/574, 4/1013. New file in force: run87_new.ini. Files run87_new_tp.ini and run87_new_pol.ini were also created. See nika2-a:~/nika_V3_IRAM.ini.
Oct. 14, 2025
We rename the ini files:
run87.ini (active file)
run87_old.ini (OLD active file, not used in August)
run87_newSweep_tp.ini
run87_newSweep_pol.ini
run87_oldSweep_tp.ini
run87_oldSweep_pol.ini
@15:00 LT we start, after preparing the whole "NIKA2 week environment architecture: 15/8/55 lost KIDs in Ar 1,2,3. Unstable sky and thick clouds coming from the N. We're entering in the peak of the tau forecast. It will be better later this evening. Meanwhile we try to focus. The old make-imbf script does not produce the imbfits files. Angel contacts Albrecht to solve the issue. The new make-imbf produces the file regularly.
