Super magnets take role in fusion research

摘要

Fusion research company Tokamak Solutions has worked with partners at Oxford Instruments, the Czech Technical University and the Institute of Plasma Physics in Prague to use high temperature superconducting magnets on a tokamak for the first time. High temperature superconductors have remarkable properties: they conduct electricity with zero resistance, even with simple cooling by liquid nitrogen; they can withstand high magnetic fields and huge current densities - and they continue to be superconducting throughout the plasma pulse in a tokamak. It has long been known that high temperature superconductors could have a role to play in the future of tokamak fusion research, but this is the first time they have actually been used for magnetic field coils on a tokamak.
