STRIP56 – Y-factor test

General information

Edit  Delete

Polarimeter STRIP56
Acquisition date
BandQ
Cryogenic?Yes
OperatorsSilvia Caprioli, Federico Incardona, Claudio Pincella
PHSW state0110
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).
