Crab crossing in a gamma-gamma collider (open access)

Crab crossing in a gamma-gamma collider

The crabbing of an incident photon beam from a laser, and the electron beam with which it interacts at the conversion point, is shown to have the same efficiency as in head-on Compton scattering, but with the advantages of a crossing geometry. The resulting {gamma}-ray beam is also crabbed, which allows for a crossing collision point, while maintaining the luminosity at the same value it would have in a head-on collision.

Crossing angles in the beam-beam interaction (open access)

Crossing angles in the beam-beam interaction

Many storage ring colliders are being designed to reach high luminosity through the use of a large number of closely spaced bunches. This introduces a potential problem of parasitic collisions near the interaction point, but these parasitic collisions can be avoided by having the beams cross at an angle rather than head-on. The contributions to the tune shifts and the beam-beam resonances introduced by a crossing angle are analyzed in this paper.

Luminosity of continuous beams with crossing angle (open access)

Luminosity of continuous beams with crossing angle

Since it appears difficult to reach a luminosity of even 10/sup 32/ cm/sup -2/ sec/sup -1/ with (p, anti p) in a single ring if the number of events per bunch collision should not exceed unity, it seems appropriate to ask what could be done with two continuous beams in independent rings, ISR style. This subject was treated at some length in the first ICFA report by Keil and King, based on an optimization procedure developed earlier by Keil. In this note, a different approach is taken by considering the length of the interaction diamond and the luminosity to be of primary importance and relating the other parameters to them.
