FormFactor - HPD Model HE-3-SSV-PT-2 - Dry Helium-3 Cryostat
-
Cryogen-free: cooling with two-stage pulse tube refrigerator (PTR)
-
Low vibration
-
Mechanical heat switch
-
Internal charcoal sorption pump
The Model HE-3-SSV-PT-2 is a single shot, cryogen-free, helium-3 cryostat for cooling samples in vacuum. It uses a two-stage pulse tube refrigerator (PTR) for initial system cool down.
Highly conductive flexible thermal links made from multiple strands of fine OFHC copper wires are used as thermal link between the two stages of PTR and both radiation shields. This design significantly reduces the vibrations that may be transmitted to the He-3 stage from the PTR.
Mechanical heat switches are used for the system operations.
An internal charcoal sorption pump is used to reduce the vapor pressure of the liquid He-3 and cool it down to its base temperature.
With our optimized design of the heat exchanger on the second stage regenerator of PTR, no additional compressor is needed for He-3 condensation.
The system is supplied with a complete set of thermometers and heaters to monitor and control the temperature of the various stages of the cryostat.
It also includes all the necessary valves and pressure gauges for safe and reliable system operation.
