Large orbit magnetic confinement systems for advanced fusion fuels
The objective of the grant/contract was to illuminate the problem of magnetic confinement for plasmas where the majority of ions have large gyro-orbits and do not obey adiabatic particle dynamics. The electrons are adiabatic. We considered a class of equilibria where large orbit ions dominate; the equilibria are rigorous solutions of the Vlasov/Maxwell equations. For a simple cse -- the infinitely long, low beta, rotating plasma a complete stability analysis was carried out. This problem was the basis of the first paper on finite Larmor radius stabilization. In that paper an expansion in {var epsilon} = {bar {alpha}}{sub i}/r{sub o} was carried out to the first significant order beyond MHD. In this report the same problem is solved to all orders in {var epsilon}. While this case is of limited applicability to experiments it is rigorous and without approximations, so that it can be used to verify approximations to be developed for more complex and useful cases. The application of the results to date to small fusion reactors is described in the second paper which was written after the termination of the contract, but is based in part on material developed during the contract period.
