One dimensional global and local solution for ICRF heating
Abstract
A numerical code GLOSI [Global and Local Onedimensional Solution for Ion cyclotron range of frequencies (ICRF) heating] is developed to solve onedimensional wave equations resulting from the use of radio frequency (RF) waves to heat plasmas. The code uses a finite difference method. Due to its numerical stability, the code can be used to find both global and local solutions when imposed with appropriate boundary conditions. Three types of boundary conditions are introduced to describe wave scattering, antenna wave excitation, and fixed tangential wave magnetic field. The scattering boundary conditions are especially useful for local solutions. The antenna wave excitation boundary conditions can be used to excite fast and slow waves in a plasma. The tangential magnetic field boundary conditions are used to calculate impedance matrices, which describe plasma and antenna coupling and can be used by an antenna code to calculate antenna loading. These three types of boundary conditions can also be combined to describe various physical situations in RF plasma heating. The code also includes plasma thermal effects and calculates collisionless power absorption and kinetic energy flux. The plasma current density is approximated by a secondorder Larmor radius expansion, which results in a sixthorder ordinary differential equation.

ON A NUMERICAL APPROXIMATION TO THE SOLUTION OF THE ONEDIMENSIONAL, ONE VELOCITY TRANSPORT EQUATION WITH ISOTROPIC SCATTERING (thesis)
A numerical approximation to the solution of the onedimensional, one velocity neutron transport equation using the method of discrete ordinates is considered. It has been shown that the discrete case is convergent for a modified GaussSeidel iteration procedure. A mathematical discussion is presented for the properties of the coefficient matrix formed by the difference equations. The various iterative procedures which may be used to solve the discrete case are discussed. (W.D.M.) 
Global ion cyclotron waves in a perpendicularly stratified, onedimensional warm plasma
The sixthorder wave equation which results from a finite temperature expansion of the Vlasov equation is solved globally in a perpendicularly stratified, onedimensional slab plasma. The diamagnetic drift and associated anisotropy are included in the unperturbed distribution function to ensure a selfadjoint system. All xdependence in the plasma pressure and magnetic field is retained along with the electric field parallel to vector B. Thus, Landau damping of the ion Bernstein wave is included as well. Because the wave equation is solved implicitly as a twopoint boundary value problem, the evanescent shortwavelength Bernstein waves do not grow exponentially as in shootingmore »
