The 20 Kelvin vacuum cryostat is a multi-shroud design, with 5 concentric shrouds, allowing efficient thermal de-coupling of the flight hardware from the external environment. The vacuum cryostat is 0.9m x 0.6m diameter.
- Dimensions: 1m diameter by 1.1m long
- Hardware mounting area: 0.4m diameter by 0.6m height
- Base vacuum pressure: 5 x 10-5 mBar
- Temperature range: 20K to 360K
- Temperature control: Closed loop PID control, ±0.2K
- Temp measurement: Eight Cernox sensors
- Temp/pressure logging: 8 channel plus pressure logging
- Electrical feedthroughs: Various micro-D
