ST-200 Non-optical (Tubular) Cryostat

The ST-200 series are cryostats with tubular tails suitable for resistivity measurements or experimental configurations where square tails are undesirable.

ST-200 tubular non-optical supertran continuous flow cryostat

Designed for non-optical experiments, the Janis Research ST-200 includes the following components:

  • Tubular vacuum shroud
  • Tubular radiation shield
  • Blank sample holder
  • One (1) 10-pin electrical feedthrough
  • Three (3) blank feedthrough ports
  • Temperature sensor
  • 6 ft superinsulated cryogen transfer line
  • Control heater
  • System test

Typical applications:

  • High Tc
  • Resistivity
  • Hall studies
  • Magneto resistivity
  • NMR spectroscopy
  • Diffractions:
    • Gamma ray
    • Neutron (please see other configurations)
    • X-ray

Also available: ST-200-NMR cryostat for NMR spectroscopy

ST-200-NMR tubular non-optical supertran continuous flow cryostat

This drawing is an application-specific variation of the tubular SuperTran ST-200 cryostat. This very specialized design includes a thermal anchor above the radiation shield for mounting electronics and a number of rotary and BNC electrical feedthroughs for access to the sample area.
