U.K. vision for fusion
The U.K. government has announced a series of initiatives to progress fusion to commercialization, laid out in a fusion strategy policy paper published March 16. A New Energy Revolution: The UK’s Plan for Delivering Fusion Energy begins to describe how the government’s £2.5 billion (about $3.4 billion) investment in fusion research and development over five years will be allocated.

A steady inductive helicity injection (SIHI) method is described that has the following properties: (a) helicity is injected at a nearly constant rate; (b) neither magnetic energy nor helicity flow out of plasma at any time; (c) no open field lines penetrate the walls; (d) the equilibrium is produced in a close-fitting flux conserver; (e) a rotating magnetic structure is produced directly; and (f) in the frame of the rotating field, the current profile is nearly time independent and nearly optimum for the application discussed. SIHI can be applied to any toroidal plasma. Application of SIHI to a high-beta spheromak is described.
