Abstract:
A computational physics simulation which models the behavior of ions in a
``trap'' was developed to study behavior of ions within Paul traps and
Penning traps, which use electric and/or magnetic fields to confine ions.
The simulation was developed, tested, and
run in Fortran 90, with the intent of porting the application to
High-Performance Fortran when a complete compiler is available. Parts
of the code were tested on ``subset HPF.'' Development of the simulation
and analysis of results required several computationally intense
algorithms, including Gear and velocity-Verlet finite difference methods,
and repeated calculation of long-range interaction forces and potentials.
At this stage of testing, it appears that the
results of the simulation agree with theory.
