Beamstrahlung is the radiation emitted by particles of one beam, as they cross the other beam in a particle collider. It has been extremely useful for monitoring at the Stanford Linear Collider, and we have tested a novel concept at CESR, which has now been developed fully for SuperKEKB. The collaboration includes also KEK (Japan), Puebla (Mexico), Sinaloa (Mexico), and Tabuk (Saudi Arabia). This page collects all papers, theses, and technical documentation.
