Open flow helium cryostat system and related method of using

An open flow helium cryostat system for cooling a sample crystal to be examined using X-ray diffraction, neutron diffraction, or a similar method. The cryostat system including a primary helium supply to provide a first stream of liquid helium onto the sample crystal and a secondary helium supply to provide a second stream of gaseous helium around at least a portion of the primary helium supply at a temperature warmer than the first stream of liquid helium to prevent the formation of ice on the sample crystal.
