Cryogen-free 3He systemCryogen-free 3He system UHV compatible

Cryogen-free ³He
System Product Code: DRYICE3

A compact cryogen-free ³He system, sample in vacuum, uses a closed cycle cooler with vibration eliminated by a bellows system. A 1K stage allows full condensation of the ³He charge which extends the hold time at a base temperature of 300mK to 40 hours, and gives a fast regeneration time. The temperature parameters for this system is 300mK to 300K across the range.

Components:

  • Closed cycle cooler, cold head, and compressor
  • Cryostat
  • 1K and 300mK low temperature stages.
  • Pumping system
  • Temperature controller (automatic) and matched sensors
  • ³He and 4He gas dumps. With gas handling manifold

Options / customisation:

  • Further vibration isolation
  • Additional wiring
  • Coaxial cables
  • Wave guides
  • Line of sight ports
  • Optical windows

The system shown is UHV compatible and designed to suit a customer's own UHV system.


Top-Loading Cryogen-free 3He System
Product Code: DRYICE3 TL

This top-loading cryogen-free 3He system, sample in liquid ³He, uses closed cycle cooler with vibration eliminated by a bellows system. A 1K stage allows full condensation of the ³He charge, this extends the hold time at a base temperature of 320mK to 30hours, and gives a fast regeneration time. The temperature range for this system is 320mK to 300K temperature control across the range. Top-loading probe with 20mm sample space.
