Cryogen Free ³He System

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: ^DRYICE^{3 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.
