Samenvatting
Electron and ion sources based on laser-cooling and trapping techniques are a relatively new
reality in the field of charge particle accelerators. The dynamics of these sources is governed
by stochastic effects, and not by the usually dominant space-charge forces. This is the direct
consequence of the extremely high initial phase-space density. Correct simulation results
require a full molecular dynamics simulation, i.e. we need to track each and every particle
including all pair-wise interactions. The two main candidates for such molecular dynamics
simulations are the Fast Multipole Method (FMM) and the Barnes&Hut scheme (B&H).
Tradeoffs are given, and simulation results for the B&H method implemented in the General
Particle Tracer (GPT) code are presented for realistic test-cases.
