Beam Equilibrium Stability and Transport (BEST) Code
Nonlinear Perturbative Particle Simulations:
Simulation noise is reduced significantly.
No waste of computing resource on something already known.
Moreover, make use of the known to determine the unknown .
Study physics effects separately, as well as simultaneously.
Easily switched between linear and nonlinear operation.
Some Computational Features:
Adiabatic field pusher for light particles (electrons).
Solves Maxwell's equations in cylindrical geometry.
Written in Fortran 90/95 and extensively object-oriented.
NetCDF data format for large-scale diagnostics and visualization.
Achieved an average speed of 80 megaflops on IBM-SP (stage I) at NERSC.
The code has been parallelized using OpenMP and MPI.
