Cryogen-free 1.5 K Continuous Closed Cycle Cryostat
Lake Shore Cryotronics environment by Janis
These Lake Shore closed-cycle refrigerator cryostats cool the sample in exchange gas. Helium circulates through an independent cooling loop to cool samples to temperatures as low as 1.5 K, allowing nearly unlimited operation. The sample space is separate from the cooling loop, minimizing the risk of blockages. With a wide range of electrical feedthrough and window options, they are a versatile choice for making cryogenic measurements without using liquid helium.
1.5 K Continuous Closed Cycle Cryostat Features
- <1.5 K to 800 K
- Cryogen-free
- Sample in exchange gas
Every cryostat comes with a Lake Shore
temperature controller and calibrated sensor.
The SHI-950-LT offers rapid sample exchange. The sample is inserted, via a long rod, into a nearly isothermal region of the gas column for cooling. Sample exchange by simply removing the sample rod, switching samples on the rod, and reinserting the rod into the cryostat. The entire sequence takes ~80 min and is performed while the cryostat is operating.
Neutron scattering configuration
The SHI-950-LT can be configured for neutron scattering. Modular tails can easily be exchanged for different experimental requirements.
