STRIP44 – Bandpass characterization

General information

Polarimeter STRIP44
Acquisition date
BandQ
Cryogenic?Yes
OperatorsSilvia Caprioli
PHSW state0101
Notes

The high HEMTs currents generate dissipation, which makes the polarimeter temperature unstable. We decided therefore to thermalize the polarimeter at 22 K (instead of 20 K).
