[PEM26-07] Loading Relativistic Maxwell Distributions in Particle Simulations

*Seiji ZENITANI1 (1.NAOJ)

Keywords:PIC simulation, relativity, Monte-Carlo

Numerical algorithms to load relativistic Maxwell distributions in particle-in-cell (PIC) and Monte-Carlo simulations are presented. For stationary relativistic Maxwellian, the inverse transform method and the Sobol algorithm are reviewed. To boost particles to obtain relativistic shifted-Maxwellian, two rejection methods are proposed in a physically transparent manner. Their acceptance efficiencies are 50% or 100%, respectively. Our simple methods can be combined with arbitrary base algorithms and arbitrary distribution functions.
