3HELIUM SYSTEMS

Model HE-3-TLSL-NMR Cryostat

Description:

The model HE-3-TLSL-NMR is a top loading system with sample in liquid He-3, with a compact design that fits typical existing NMR magnet systems.  The sample can be top-loaded into the He-3 chamber, while the cryostat stays cold, and in the room temperature bore of the NMR magnet.  A sample probe and vac-lock system are included, along with an external gas handling system for safe and quick sample insertion and removal in and out of the He-3 sample chamber.

This He-3 cryostat includes the following components:

  • Charcoal sorption pump with heater and thermometer
  • 1 K pot with thermometer
  • Top loading sample probe with vac-lock system
  • Thermometer and heater on the sample probe
  • External gas handling system with stored He-3 gas
  • Operation test

Options:

  • Resistive and/or superconducting wires
  • Coaxial cables
  • IVC tail for superconducting magnet
  • Low eddy current cold finger
  • Automatic temperature controller
  • Helium level sensor and read out
  • Nitrogen level sensor and read out
  • He-3 pot with heater and thermometer
  • Liquid nitrogen shielded dewar
  • Liquid helium transfer line

 

Performance Specification:
Base Temperature: 300 mK
Holding Time at Base Temperature: 24 hours
Sample Space: 0.5" - 1.0"
Temperature Range: 0.30 K - 80 K
