Numerical Modeling of Thermalization of Positrons in Gas-Filled Surko Traps

Marjanovic, S; Suvakov, M.; Bankovic, A; Savic, Marija; Malovic, G.; Buckman, Stephen; Petrovic, Z Lj


In this paper, we present the results of our Monte Carlo-based numerical simulation of a Penning-Malmberg-Surko positron trap. The results of simulations show the effect that various processes (such as positronium (Ps) formation, annihilation, losses on walls, etc.) have on trapping efficiency. The thermalization profile is shown, along with the evolution of the energy distribution that morphs from a particle beam to a broad swarm-type distribution.
