Design, construction, and test of a 113-mm bore solenoid with NbTi cable-in-conduit superconducting windings
The authors constructed a solenoid using a cable-in-conduit type conductor with NbTi composite and copper strands as a focus for practical conductor fabrication techniques and coil winding methods using such conductors. The finished coil provides the opportunity for global tests of the performance of this type of conductor in a real coil that produces high fields and uses a long section of conductor. The cable is a concentric, containing 19 triplex strands made from 0.7-mm-diam wire. The superconducting strands are contained entirely within the outer layer of the cable and thus are fully transposed. The cable is jacketed with stainless steel tubing; the overall conductor diam is 8.6 mm. Induction heaters, voltage taps, pressure taps, and temperature sensors are installed in the windings to aid in stability measurements. Flow to the coil is provided by a blowdown system or a piston pump. Details of conductor and coil fabrication are presented. 5 refs.
