Results and analysis of the hot-spot temperature experiment for a cable-in-conduit conductor with thick conduit

Pierluigi Bruzzone, Kamil Sedlák

In the design of future DEMO fusion reactor a long time constant (similar to 23 s) is required for an emergency current dump in the toroidal field (TF) coils, e.g. in case of a quench detection. This requirement is driven mainly by imposing a limit on forc ...

Superconductivity and fusion energy—the inseparable companions

Pierluigi Bruzzone

Although superconductivity will never produce energy by itself, it plays an important role in energy-related applications both because of its saving potential (e.g., power transmission lines and generators), and its role as an enabling technology (e.g., fo ...
