4 Kelvin
Closed Cycle Refrigerator Systems
from Janis and SHI

Janis Research can provide specialized 4 K cryostat systems for operation over very wide temperature ranges (<2 K - 800 K).  Different cryostat window options can be offered to allow experiments from the far-IR to gamma-ray regimes.  The physical dimensions of our cryostat systems can be varied to give the required internal space for any experiments, and the outer vacuum shrouds can be modified to fit within the bore-gap of today's smaller, more powerful magnet systems.

Possible designs include:

• Cold-plate cryostat systems for experiments requiring larger sample volumes

• Systems for matrix isolation experiments requiring the introduction and freezing of gas samples

• UHV sample environments and UHV chamber integration

• Cryogen free superconducting magnet systems

• Systems configured for helium droplet experiments
