Development of an Advanced Simulation System for the Analysis of Particle Dynamics in LASER based Protein Ion Sources

A. Hieke
Ciphergen Biosystems, Inc., US

Keywords: protein, ion dynamics, Monte Carlo simulation, GEMIOS, collisional cooling, FEM, DSMC, ANSYS

Abstract:
An advanced multi-physics simulation system henceforth referred to as GEMIOS (Gas and Electromagnetic Ion Optical Simulator) has been implemented which allows the computation of 3D trajectories and energy exchange of ion beams/clouds under the influence of 3D time-dependent external electromagnetic fields in the presence of 3D rarefied gas flow fields and has therewith capabilities beyond existing tools. GEMIOS achieves its unique capabilities by utilizing commercial (ANSYS) as well as special purpose codes (FORTRAN). The fundamentally novel aspect of GEMIOS is that it combines electromagnetic field solutions and fluid dynamic field solutions obtained within a given domain to compute charged particle trajectories.
