Development of a line superconductor made of niobium carbonitride filaments
Abstract
A technique for the vapor deposition of niobium carbonitride on an inert substrate in the form of a filament (dia. 7 microns) was developed. The bundling of these filaments and their impregnation with an antidiffusion copper barrier was then studied. The superconducting and mechanical characteristics of these filament bundles were determined. Results show that the method is practicable. A bundle of 3000 carbon filaments was prepared, then coated in niobium carbonitride. However, over any significant length of the obtained line the superconducting characteristics were not constant. The adhesion of the superconducting coating to the filament bundle was also unsatisfactory.
