Abstract:
Wall plasmas, plasmas in contact with a solid wall, are studied in two basic cases. The first is a linear theta-pinch. In this geometry the motion of the plasma along the field lines and the transfer of heat along the field lines is investigated using a transient hydrodynamic heat flow model and a steady state heat flow model. Good agreement is found with experimental results on the Scylla IV-P linear theta pinch. Results of the stationary model are used to estimate linear fusion reactor lengths. Results are that linear fusion reactors would be shorter for low atomic number (Z) end walls, but have higher linear power levels (power per unit length) for high Z end walls. The second case is a stationary solution of the structure of a plasma in contact with a diverter or limiter in a tokamak. This geometry is investigated to determine relationships between plasma density, temperature and the velocity of plasma flow toward the diverter. Solutions are found and sensitivities are presented.
