Cryostat adopting a pulse tube refrigerator Home
Vibration is reduced by using a pulse tube instead of GM fridge.
There are following 4 types of cryostats based on different refrigeration
1． Cooling by pulse tube 2nd stage 3 - 300K
2． Cooling by 4He pumping 1.5 - 300K
3． Cooling by 3He pumping 0.5 - 300K
4． Cooling by dilution refrigerator 0.02 - 300K
