Revision as of 13:38, 1 December 2011
NEW
- Squid-Wiring for one two-stage Squid
- Two Lemo plugs and four coax-feedthroughs on top of cryostat.
- RuOx-000 Thermometer on lower MC platform.
- New Still-heater!! old one was broken? New resitance RSTILL=1.13k.
- New Noise-Thermometer mounted on Demag-Stage read out by two Squids.
Tests
Summary
- 30.11.11: COOLING DOWN
- 10:30 : Start closing Cryo
- 14:00 : Dewar closed , start pumping dewar. All lines pumped, all pumps tested.
- Exchange gas: pVC=10mbar.
- 15:00 : Start filling nitrogen
- 17:12 : Dewar Pt-100 shows LN.
- 01.12.11: START COOLING WITH LHe
- 08:00 : Continue filling with LN until TDewar=78K, continue for 5 minutes.
- 10:45 : Pump dewar (-0.8bar), float with He from recovery line
- 11:00 : 1st can of LHe connected, start 1K-pump (TDewar=121K, TMC,Si-Diode=206K, pVC=3mbar, TMagn,u.=176K
Checking Filterboxes
- done!
- details will be added :)
