The Beam Equilibrium Stability and Transport (BEST) code is a three-dimensional, multi-species, nonlinear delta-f particle simulation code used for studying collective effects in high-intensity particle beams with applications to high-intensity accelerators, and ion-beam-driven high energy density physics. It has been developed by the Princeton beam dynamics group, and has been parallelized using the MPI protocol, and scales linearly up to 512 processors. The BEST code has been used to simulate the electron cloud instability in the Proton Storage Ring experiment at Los Alamos National Laboratory , as well as the Spallation Neutron Source at Oak Ridge National Laboratory , as well as collective instabilities driven by energy anisotropy in one-component intense charged particle beams .
