The engineering design of the HT-7U tokamak

The HT-7U tokamak is a Chinese National Meg-science Engineering Project designed to develop scientific and technological basis for the tokamak fusion reactor. HT-7U has a long pulse (1000 s) operating capability, flexible PF system and auxiliary heating and current drive system making it a good facility for advanced performance experiments. This paper provides an overview of the HT-7U project and describes the engineering design of the tokamak and sub-systems.
