I am thinking about the fusion in a Tokamak device, where -because of the instabilities - the magnitic confinement is not sufficient to ignite and sustain the fusion process. There is no possibility to apply the ablation like in the H bomb, or in the inertial fusion systems with frozen DT pellet. Therefore I think about an additional force of compression, that would be the X-ray radiation, obtained from the conversion of a high power laser beams. There are 100kW-1MW laser sources like the Nova and Vulcan devices, but who can calculate the radiation pressure obtained from an 1MW power laser source? What is the physical relationship between the radiation power and the developed radiation pressure? It is possible, to apply the magnetic conifenement and the radiation pressure together?
