Object Oriented Formulations for particle-in-cell (PIC) Simulations
Abstract
Two 1d3v versions of XOOPIC were made, one directly from our 2d3v OOPIC, and the other, from scratch WHICH IS ATTACHED, DONE MOSTLY BY A VISITOR, Dr. H. Usui, from Japan (wholly paid by his home institution). We are in the midst of improving XOOPIC with respect to microwave tubes by replacing non-e-beams regions with equivalent lumped element circuits. We demonstrated quite a few means, physical and numerical, for speeding up particle codes (PIC-MCC) by factors of up to 10 to 100. We also made a model/simulation to measure particles leaving a plasma, especially ions, in order to obtain their energy distributions and velocity angeles (called IED and IAD), as a function of the ratio of ion transit time THROUGHOUT THE PLASMA EDGE (SHEATH) relative to the period of the RF driving the plasma. While we have a good idea of the stability and accuracy of our ES and EM simulations in general (e.g., in Birdsall and Langdon text), it pays us to re-examine the cause and cures of errors of the Maxwell set the Newton-Lorentz set of equations, especially for relativistic particles.
