Beamstrahlung as a Beam-Beam Diagnostic

Beamstrahlung is the radiation from one beam of charged particles in a storage ring caused by its interaction with the electric field of the other beam. This radiation carries a great deal of information about the structure of the two beams, and thus can be used to measure, for example, the size of the beams and how close they come to head on collision. Needless to say this can be extraordinarily useful in optimizing the luminosity in colliders. Below is a collection of notes written or co-written by members of our group on beamstrahlung.
