STRIP44 – Y-factor test
General information
| Polarimeter | STRIP44 |
| Acquisition date | |
| Band | Q |
| Cryogenic? | Yes |
| Operators | Silvia Caprioli |
| PHSW state | 0110 |
| 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).
