The basic concept and techniques of the one-dimensional electromagnetic particle code:KEMPO1 [Omura and Matsumoto, 1993] are reviewed briefly. Special characteristics of the code are enhanced electrostatic thermal fluctuations that often interfere the physical processes to be reproduced in the particle code. From a simplified analysis on the fluctuations, a criteria for the grid spacing is given. A modification of the KEMPO1 for solution of the relativistic equation of motion is also described. Since the essential part of the code is very simple and short, the KEMPO1 code is implemented with the MATLAB software, using the powerful graphic library. Explanation of the input parameters for the relativistic KEMPO1/MATLAB code and several examples of the applications are given. |
