November 11th 2013, Alain Benoit, Martino Calvo and Andrea Catalano come to the 30m to install, cool down and testing the NIKA prototype.
12-13 November 2013: cooling down, HWP Modulator installation at the pupil (120mm from the entrance lens of the cryostat)
14 November 2013: OTF geometries on Mars and Uranus. Check of the focal plane geometry. First light of NIKA prototype with polarisation facilities.
15 November 2013: Cryostat back to 300K: 3He-4He mix recovery, heating trap. Polarisation facilities dismantling. Back to Granada.
STATUS
Cryostat Temperature: 150mK (set by temperature control).
Arrays status: 128 pixels 2mm - <1Hz/sqrtHz noise; 201 pixels 1mm about 10Hz/sqrtHz noise
Modulation frequency: 8kHz 1mm, 4kHz 2mm
OBSERVATIONS Log
Opacity is measurd with the taumeter at 225 GHz
p2cor : 0
p7cor : 0
