3D PIC method development for simulation of Beam-Beam effects in supercolliders

A new Beam-Beam simulation code based on a 3D PIC method has been developed. Taking into account to the full extent the three-dimensional nature of interaction can be useful for studies of a pinch effect at large crossing angles in ILC and Crab Waist properties in SuperB Factory. The numerical examples of the electron and positron bunches movement and collision simulation are presented.
