COMPUTER SIMULATION OF PLASMA INJECTION AND TRAPPING IN A LINEAR OCTUPOLE.
Abstract
The plasma model used in the simulation is a particle-like model. Several restrictions are placed on the model in order that it faithfully simulate the plasma. These restrictions are discussed in detail. The motion of the particles is determined by Newton's equation of motion and the Lorentz force law. The difficulties involved in computing the Coulomb interaction of the particles are discussed. An alternative procedure for computing the electrostatic particle interactions by solving Poisson's equation is presented. A technique for machine solution of Poisson's equation is described in detail. The method is a modification of the technique given by Hockney. The computer techniques are applied to the study of the injection and trapping of a plasma in a linear octupole. The results of this analysis are presented and compared with the experimental results of Boyd. Physical arguments are given to explain the analytically and experimentally observed phenomena. (Author)
