BBC: Program for Beam-Beam Interaction with Crossing Angle

by Kohji Hirata

Description

BBC is a FORTRAN code for simulation of the weak-strong beam-beam interaction. The beam-beam interaction is treated in a symplectic (in 6D sense) and accurate way including crossing angle effects. The code can be used both for electron and proton rings with linear one-turn map for the arc.
