Cryogenfree 3He System

Cryogenfree 3He
System Product Code: ^DRYICE³

A compact cryogenfree 3He system, sample in vacuum, 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 300mK to 40hours, and gives a fast regeneration time. The temperature range for this system is 300mK to 300K temperature control 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 the customers own UHV system.

Top Loading Cryogenfree 3He System
Product Code: ^DRYICE^{3 TL}

A top loading cryogenfree 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.
