Description
The novel uni-layer concept for superconducting magnets introduces a new geometrical approach to form a magnetic field orthogonal to an aperture. The new design allows for independent single layers, eliminating the need for internal layer jumps and favoring the use of grading, while maintaining high efficiency in the use of conductor. The unique attributes of the uni-layer concept are particularly advantageous for high-temperature superconductors, especially for those that are strain-sensitive and prone to winding degradation, in very high field accelerator magnet applications, that require high efficiency and compact aperture.
This paper presents an overview of the developments at the Lawrence Berkeley National Laboratory (LBNL) regarding the first demonstrators and magnets based on the uni-layer concept. The various magnet designs, based on CORC®, STAR®, and Bi-2212 conductors are conceived as insert magnets for the LBNL Nb$_3$Sn CCT 6 (Canted Cosine Theta) magnet, with a combined 16+ T in the hybrid configuration. The conceptual designs will be presented, including the main features of the magnet, winding geometry, bore and peak field, and main dimensions and characteristics of the support structure.
