Abstract: A persistent current switch system is presented. One embodiment of the persistent current switch system includes a vacuum chamber having a winding unit and dual cooling paths. The dual cooling paths are configured to circulate a coolant flow. The dual cooling paths are defined by a first cooling path and a second cooling path. The first cooling path includes a solid thermal component disposed in direct contact with the winding unit and the second cooling path includes a cooling tube disposed in direct contact with the winding unit and configured to circulate a coolant therein. The dual cooling paths cool the temperature of the winding unit below the threshold temperature to transition the persistent current switch system from the first mode to the second mode. A method of for cooling a winding unit in a persistent current switch system and a switching system including dual cooling paths are also disclosed.

Abstract: In embodiments of the invention, a superconductor lead is configured to have less ohmic heating by its own current and less heat conduction from room temperature to cryogenic temperature, where a cryogenic apparatus is located. The superconducting lead with no ohmic resistance and low thermal conductivity disclosed herein maximizes current capacity by placing superconductors in parallel, each having equal current. Thus, the resistances are controlled to provide uniform current distribution through each superconductor of the high temperature superconducting (HTS) lead.

Abstract: A current lead assembly for minimizing heat load to a conduction cooled superconducting magnet during a ramp operation is provided. The current lead assembly includes a vacuum chamber having a through hole to enable a first end of a current lead contact to remain outside the vacuum chamber and a second end of the current lead contact to penetrate within the vacuum chamber. A vacuum boundary wall is located between the vacuum chamber and the current lead contact. At least one superconducting magnet is arranged inside of the vacuum chamber and includes a magnet lead. A second end of the current lead contact is coupled to the magnet lead via an internal lead. A vacuum cap is removably disposed to sealingly encompass therein the first end of the current lead contact during a first state of operation. The first end of the current lead contact is arranged to contact a power supply during a second state of operation, wherein the contact occurs exterior the vacuum chamber.

Abstract: Provided are techniques that may include a disposable magnetic cell isolation holder having one or more passages that accommodate a magnetic retention material to facilitate magnetic cell isolation without adjustment of magnetic field parameters between isolation procedures using different magnetic particle sizes. When the magnetic cell isolation holder is coupled to a magnetic field generator, a first passage corresponding to a smaller particle size is positioned in a magnetic field where the magnetic field characteristics are different relative to a second passage, of a second holder or in the same holder, for use with another bead size.

Abstract: A superconducting magnet includes a cooling tank containing a cooling medium and at least one superconducting circuit configured for generating a magnetic field. The superconducting magnet further includes a power supply connected to the superconducting circuit(s) for energizing the superconducting circuit(s) and a superconducting switch electrically connected across ends of the superconducting circuit(s). The superconducting switch includes a superconducting winding and a thermal conduction member having a first end thermally coupled to the superconducting winding and a second end thermally coupled to the cooling medium within the cooling tank. The thermal conduction member includes, at least, a first layer and a second layer. The first layer is constructed of a metal material having a first thermal conductivity. The second layer supports the first layer and is constructed of a material having a second thermal conductivity that is lower than the first thermal conductivity.
