In the case of ARC and SPARC, this would have to be done using ... Whether ARC, another tokamak design, or perhaps a stellarator derived from the Wendelstein project will be the first to show ...

The Globus-M2 spherical tokamak that Bakharev his team are working on may be an important first step towards this goal. Tokamaks confine plasma – a hot, ionized gas – using magnetic fields ...

A gyrotron, which uses Electron Cyclotron Resonance Heating (ECRH), solves one of the key challenges for a spherical tokamak – limited space for a central solenoid, which would otherwise be required ...

At the same time, a large international group is busily constructing the massive ITER tokamak test reactor in ... towards their demonstration reactor: SPARC.
