STRIP64 – Long acquisition repeated
General information
| Polarimeter | STRIP64 |
| Acquisition date | |
| Band | Q |
| Cryogenic? | Yes |
| Operators | Claudio Pincella |
| Description | Long acquisition repeated |
| PHSW state | switching |
| Notes | The source data file was «SCI180508_145919 - STRIP64_1_f__PS-default_15hours_08May2018.txt» (90159 kB) High noise level is present on the detector output and this issue has been analyzed more deeply in two steady state tests. Conclusion is that the behaviour could improve when using the actual chain without T-Magic, therefore with feed-horn and OMT. |
