Improvements to the standard fusion reactor

1) Line up the axis of rotation, around which the particle stream is flowing, to be parallel to the axis of the Earth’s rotation. This will the effect of not subjecting them to forced precession.

2) Divide the torus into quarters and place long strait sections between them, creating a square plasma channel with rounded corners. Thus the lossy corners, where the plasma is forced to change direction, becomes a fraction of the total plasma length.

More speculatively.

3) Mirrors could be placed at each corner to reflect the light that comes up one strait section down the next. The idea would be. a) to keep the light energy in the system, so it can help to heat the plasma, by Compton scattering. b) if it is possible to achieve sufficient amplification by stimulated emission, then more of the light would travel round with the plasma. reducing the radiant heating of the chamber walls.

4) The mirror at one corner could be split and off set such that light travelling in the same direction as the plasma sees a complete mirror and is reflected round, but that light travelling in the opposite direction sees a mirror with a gap in it and part of the light is lost. The hoped for advantage of this would be that the Compton scattering would be taking place preferentially in one direction, further accelerating the plasma and any neutron that are present.

5) 3 and 4 could be repeated for xrays by using grazing angle mirrors, in long curves between the parallel strait sections.
