Preliminary Engineering Design of Toroidal Field Magnet System for Superconducting Tokamak HT-7U

摘要

HT-7U is a large fusion experimental device. It will be built in the Institute of Plasma Physics of Chinese Academy of Sciences. The mission of HT-7U is to develop the scientific Basis for a continuously operating tokamak fusion reactor. This paper describes only a toroidal Field (TF) superconducting magnet system of HT-7U. In this paper, design criteria of conductor And stability analysis, coil winding and support structure design of magnet system, mechanical Calculation and stress analysis, heat load evaluation are given.
