Optimization of the beam crossing angle at the ILC for e+e- and gamma-gamma collisons


  • Prof. Valery TELNOV

Primary authors


In the present ILC design the beam crossing angle for e+e- collisions is 14 mrad. The photon collider needs the angle about 25 mrad due to larger beam disruption angle. The solution is suggested which decreases the required crossing angle for the photon collider down to 20 mrad and allows to work in both modes of collisions without any degradation of performance.
