Closed-Cycle Cryostats

Rapid Sample Swapping for Powder Diffraction

A closed-cycle cryostat is a temperature-controlled chamber used to study temperature-dependent phase transitions and structural changes. It uses a closed-loop system with a compressor and a cold head, where compressed gas expands to create cooling, maintaining a cold environment.

The absence of liquid gases like helium or nitrogen and the ability to quickly swap samples make these closed-cycle cryostats a popular choice for flat plate powder diffraction experiments.
