> MacSimion is a program for the numerical simulation of the motion of
> charged particles in electric and magnetic fields.
>
> MacSimion consists of three subprograms. The first is the geometry
> sub-program, which allows one to construct an arrangement of up to
> 127 distinct electrodes, each with its own electrical potential.
>
> The second "refine" subprogram takes as input the electrode
> arrangement defined in the geometry subprogram and by iterative
> application of Laplace's equation it solves for the electrical
> potential at all points in the two-dimensional array that represents
> the space in and about the electrodes.
>
> The "trajectory" part of the program takes as input the results of
> the refine procedure, and along with data specifying the initial
> conditions of an ion, calculates the trajectory of that ion in the
> vicinity of the electrodes.
