TPX superconducting PF magnets

Abstract

The Westinghouse team has extended the Lawrence Livermore National Laboratory advanced conceptual design for the TPX PF magnets through preliminary design. This is the first time superconducting PF magnets have been designed for application in a tokamak. Particular challenges were encountered and solved in developing the coil insulation system, welding the helium stubs, and winding the coil. We fabricated a coil using copper stranded CIC conductor, to surface manufacturability issues and demonstrate our solutions.In the paragraphs that follow, we describe aspects of the PF magnet system preliminary design, and discuss our solutions to some of the most challenging aspects of the preliminary design.

TPX superconducting cable-in-conduit 1995 design and development progress

“…An overview of the TPX Magnet System is presented by G. A. Deis, et al [l] and the Poloidal Field (PF) system is discussed by H. Calvin, et al. [2] elsewhere in this conference. All of the TPX coils will use Cable-in-Conduit-Conductors (CICC) cooled with flowing supercriticd helium.…”
