A coil system for inductively heating a superconducting magnet in order to provide an internal energy dump by uniformly quenching a high performance superconducting magnet. The quench-inducing system uses AC magnetic fields that require negligible reactive power. The system is especially suited for inducing a relatively uniform quench in dry superconducting magnets.

In one embodiment the present invention is a Flexible Connector Assemblies (FCA)that comprises top and bottom plates connected by Flexible Connectors (FC)and provides a compliant electrical joint between the first terminal leadand the second terminal lead. These terminal leadsandare connected to the top and bottom plates eccentrically in such a way that the total currentthrough the FCA is more evenly distributed among the FCthan when the leads are centered on their respective plates. This improvement in uniformity reduces the maximum current carried by any one FC, which substantially extends the operating life of the component.

A sensing apparatus for use in a mass flow rate sensor for measuring a fluid flow rate includes a main conduit for containing a fluid flow, and a capillary tube for tapping a portion of the fluid flow from the main conduit at a first location, and returning the portion of the fluid flow to the conduit at a second location. The capillary tube is disposed about a centerline, and includes an inner wall defined by an inside radius measured from the centerline. The inside radius varies periodically, preferably sinusoidally, along the centerline for at least a portion of the capillary tube, thereby forming a turbulated surface on the inner wall. The turbulated inner wall increases wall surface area, and fluid mixing. The resulting increased heat transfer rate decreases the error in sensor output from nonlinear behavior.
