So how does it not melt its containment vessel?

So how does it not melt vaporize its containment vessel and everything around it?

The containment isn’t a “vessel”, it’s a magnetic field :)

Vacuum and magnetic fields keep it from touching anything solid.

The small scale limits the absolute energy and dissipates the energy into the plasma, and the plasma is kept away from contact with the vessels by an extremely strong toroidal shaped magnetic containment field interacting with the electrically charged plasma. Past experiments failed when the magnetic field failed to contain the plasma and permit a sustained reaction.
