NIKA October 16th, 2015 / S1

Back to list of day to day logbook of observations

2015-10-16

Following not updated

.Cryostat Temperature: 170mK cooling down slowly Arrays status tonight: full 2mm array - 1-3 Hz noise; 2 feed lines on 1mm array 3-5Hz noise Modulation frequency: 10kHz 1mm, 5kHz 2mm

For this session Array 3 is connected, but still less stable than the others.

Opacity is measured with the new taumeter at 225 GHz

Nasmyth offsets : 0, 0

Set Focus : we start at 0.0 mm We updated ini.pako. Remember 1mm difference between the focus of NIKA and the focus of the other IRAM instruments due to the design of the optics (SL).

Quick description of the session: focus tests.
