Preliminary design of a compact superconducting solenoid, for material science applications
Abstract Innovation on new materials is strongly associated with different techniques and technological developments used on the growth and characterization of samples. Recent studies suggest that one could increase the preferable orientation of the crystals, while they are being formed on the substance, by applying a strong magnetic field. Uncertainty on the magnetic field magnitude, time of exposure, and temperature requirements, impose a challenge from the technological perspective. An upper boundary of 10 T provides a wide enough range for researching the material’s growth. In this work, we present a preliminary design of a 7 Tesla superconducting solenoid. The solenoid uses NbTi cable-in-conduit technology for the windings. The proposed geometry incorporates an experimentation chamber, thermally isolated from the cryogenic solenoid windings, for magnetic stimulation of samples. The sample could be exposed to a temperature gradient ranging from ambient temperature to 200 C, as required by some substrates. We applied an optimization process to reduce the required superconductor and expand the magnetics field uniform from 3 cm wide x 3.5 cm high to a region 3 cm wide and 10 cm tall, large enough to stack their samples vertically. A magnetic force study assisted in determining the election materials for the support structures.
