Abstract
Retractable cryogenic leads for superconducting magnets are provided for making low resistance contacts at liquid helium temperature reliably in the presence of heavy frost. A tube defining a bayonet socket on one end extends through a vertical stack cover of a cryostat insert to engage and disengage a vertical terminal rod having a transverse pin. A copper rod is slidable mounted inside the tube and is vertically displaced relative to the tube by a hydraulic actuator having a housing secured on the other end of the tube. A piston is slidably mounted in the housing. After the bayonet socket engages the pin of the vertical terminal rod, the piston when extended from the housing can force the copper rod against the top of the vertical terminal rod.
