Special session before the beginning of the NIKA2 Pool - Summer 2022

10:30-13:00; Martino, Alessandro, Dave, Santiago, Angel: (transcription of the e-mail from Martino) "(...)this morning we have prepared the new sweeps for NIKA2. They are ready to be used: when starting the acquisition with the config file 'run73.ini' you'll get the 'new sweep'. To use the 'old sweep', you have to use the 'run72.ini' configuration file. Unfortunately, it looks like tonight the opacity could be pretty high, but let's hope for the best. Just as a reminder: the new sweep is made with the cryostat window closed."

Before the official time for starting the scheduled tests of the Pool, we started the DAQ to get some samples of noise traces (NIKA2 window still being closed, telescope stopped due to bad weather) using the run72.ini ('old sweep') and run73.ini ('new sweep') configuration files. Corresponding screen-shots are given below.

Monitor status and noise traces, 'old sweep', bad KIDs Ar1: 36/1055; Ar2: 172/573; Ar3: 39/1056.

Monitor status and noise traces, 'new sweep', bad KIDs Ar1: 31/1061; Ar2: 7/581; Ar3: 57/1077.

18:00-XX; Angel: tonight's plan includes a discrete pointing session, getting beam maps and other calibrations. If conditions are cool, we would start science observations. Unfortunately, telescope is stopped since 13:30 (rainy, foggy). At 18:00, tau_225GHz > 1 with thick cloud intervals.
