Beam-beam simulation for the single-pass collider

The beam-beam interaction for the single-pass collider has been investigated by means of a computer simulation. The collision of a single intense bunch of electrons with a single intense bunch of positrons has been simulated using a macroparticle code in which the interaction between each two macroparticles is calculated directly. The simulation reveals the pinch effect of one bunch upon the other, the luminosity enhancement due to the pinch effect, the attraction between offset bunches, and the large opening angles of particles in the disrupted bunches. Finally, the effects of synchrotron radiaton emitted during the collision are simulated
