Gifford-McMahon
With or without optical access
DC wiring, RF cables, optical fibers
and custom feedthroughs
< 3 K, cooldown time less than 2 h 30 min
Spectroscopy, transport, magneto-transport
Both versions share the same upper GM cryostat body, including the cryocooler, DC wiring, temperature-control interfaces and optional feedthroughs. The lower section is customized according to the experimental use case.
1
Lower user section with lateral optical windows for spectroscopy and optical measurements. A wide choice of window materials is available depending on wavelength range and experimental
