Cryogenic systems for synchrotron facilities
ST-400
The Lake Shore ST-400 continuous flow cryostat has long been a synchrotron standard for providing cooling in a UHV environment. This versatile cryostat operates with liquid helium or liquid nitrogen, and with the RGC recirculating gas cooler, it can be cooled without the need for cryogens at all.
- <4 K to 500 K operation (800 K optional)
- Extensive worldwide customer base
- Proven to 10-11 Torr vacuum
- Fully bakeable to 200 °C
- High-efficiency design operates with liquid helium or liquid nitrogen
- New or existing systems upgradeable to cryogen-free with the addition of a recirculating gas cooler
- Overall length, cold finger, and thermal shield diameters are custom configured
- Highly configurable design with UHV electrical wiring access (multi-pin or coaxial) available
- Compatible with standard UHV manipulators
- Internal control thermometer and heater are not exposed to chamber vacuum
