Flow Cryostat Probe Station
The ARS PS-L Flow Cryostat Probe Station uses Liquid Helium or Liquid Nitrogen as the cooling agent to reach cryogenic temperatures of 4 K or 77 K depending upon the cryogen used.
The core of the system is the same for both the Liquid and Closed Cycle Probe Stations, which enables the Flow Cryostat to be removed from this system and replaced with a Closed Cycle (cryogen-free) configuration at a later point, if your needs change.
ARS manufactures both the Helitran Helium transfer system and the probe station. This integrated approach ensures consistent performance and also facilitates diagnostics and service of the integrated system.
