Development of Current Leads of a Facility for Testing Coils of Thermonuclear Devices

Abstract

Development of thermonuclear devices requires constant experimental iterations both at the level of constructional materials and at the level of whole systems and their elements. Building testing facilities able to perform superconducting magnet systems of a thermonuclear reactor test is an important task of high priority, since providing certain experimental options can shift the whole concept of thermonuclear energy development. Powering systems of such facilities are the key elements that define the specialization of the facility as a whole. This article describes the structural parts and development process of 40 kA HTS current leads that are under construction for superconducting coils of various sizes intended for use in testing facilities.
