Mechanical Cryostat for Characterisation of Advanced Materials Down to 4K

A cryogenic mechanical test station comprising of a 250 kN hydraulic test frame and a 250 kN load rated cryostat. The cryostat must be suitable for mechanical testing at 4K by immersing test rigs in liquid helium, at 20K in gaseous helium, at 77K in liquid nitrogen and room temperature. The mechanical test frame must have a top mounted hydraulic actuator with sufficient working distance to enable the halves of the cryostat to be separated on specimen removal and loading. Liquid helium and liquid nitrogen dewar feeds are required.
