Practical Nb3Sn wires are still under improvement for high field applications such as accelerator, nuclear fusion, NMR and so on. Recently, the increase of non-Cu Jc are required for the future circular collider (FCC). In addition, the strengthening of the Nb3Sn wires...
The Spherical Tokamak for Energy Production (STEP) is an ambitious public programme to deliver a UK prototype fusion power plant alongside a pathway to commercial deployment. One of the primary technical challenges facing the programme is the development of the unprecedented scale high temperature superconducting (HTS) magnets required by the reactor concept design.

ABSTRACT
A fusion demonstration (DEMO) reactor requires toroidal field (TF) coils larger than those used in ITER and can withstand higher electromagnetic forces. This creates significant challenges regarding the manufacturability of the TF coils, the increased electromagnetic...
A notable progress has been made over the last decades in REBCO conductor and magnet technologies. Now multiple companies routinely deliver commercial-level REBCO conductors in different recipes, while various REBCO “user” magnets are currently under construction and some are even in routine service, though at low magnetic fields mostly less than 20 T. Despite the outstanding achievements by...
Cold test is crucial to mitigate the operation risks for the fusion magnet system. In order to fit the test requirements for the next generation fusion device BEST under construction at ASIPP, a serials of SC magnet testing facilities are being built to perform the large-scale SC magnet research on mechanics, thermology and electromagnetics properties and evaluate the SC magnet system...
Korean Fusion Energy Development Promotion Law (FEDPL) was enacted in 2007 to promote a long-term cooperative fusion research and development among participating industries, universities and research institutes. As a following step, a conceptual design study for a steady-state Korean fusion demonstration reactor (K-DEMO) has been initiated in 2012. As a result of a conceptual design study for...
Deuterium and tritium reaction generates 14 MeV neutrons and most of the generated neutrons are captured by blankets and plasma vacuum vessel (VV) and the energy of these neutrons will be exchanged to electricity. The rest can penetrate the components and reach superconducting (SC) magnets outside of the VV. A recent study on neutron mapping in fusion reactors has expanded to include thermal...
A summary of the session on the development of fusion magnets in the world is given from the seven talks and the overall discussion. The session covers the topics on “Development of LTS and HTS wires”, “Magnet development for national projects”, “Magnet development for public-private partnership”, “Test facilities”, and “Irradiation”. Highlights from the talks are reviewed, and the future...
