Cryogenic systems for synchrotron facilities

ST-400

The Lake Shore ST-400 continuous flow cryostat has long been a synchrotron standard for cooling in a UHV environment. This versatile cryostat operates with liquid helium or liquid nitrogen, and with a recirculating gas cooler, it can be cooled without the need for cryogens.
