Compact tokamak represents an economical solution for fusion energy, leveraging the latest plasma physics discoveries and advanced technologies such as high-temperature superconductors. ENN have been dedicated to fusion technology since 2018. We focus on a commercialization-oriented strategy combining economical fusion fuel p-B11 and compact tokamak. The requirements for p-B11 fusion are much harder than D-T fusion, which is being developed by most fusion research groups. However, p-B11 fusion is clean, and its fuels are easy to attain, all of which qualify p-B11fusion as a more suitable technology for commercialization.
To achieve p-B11 fusion, a very compact tokamak is essential requiring both high magnetic fields (>12 Tesla) and high current densities (>100 A/mm2). By studying the successful cases, including the ones done by Tokamak Energy UK and Commonwealth Fusion Systems US, we developed our special design to avoid tension accumulation in large HTS magnets by inserting plates to separate HTS coils.
We are fabricating two 1-meter-tall HTS coils to validate our design, one for the winding techniques and one for the 12 Tesla high field testing. Both coils are to be wound, assembled, and tested before the end of this year. By the conference opening, we will have collected testing data and these data and results will be presented on the ISS conference. Hope this is useful for the fusion community to boost the development of fusion technology.
