Adiabatic equilibrium calculations of majorradius compression in a tokamak
Abstract
Equilibrium calculations which conserve adiabatic quantities (magnetic fluxes, particle number and entropy) during majorradius compression in a tokamak have been made by using a fluxsurfaceaveraged description of the plasma behavior in order to solve the twodimensional plasma equilibrium equation. Boundary conditions are chosen to avoid skin current formation during compression, and the changes of the Ohmicheating flux required to maintain this condition are determined. Comparisons are made between the plasma parameter variations determined from these computations and the scaling behavior predicted by a largeaspectratio approximation to the adiabatic constraints.
