Abstract

Wepresentthedesignofaphoton–photoncolliderbasedonconventionalComptongammasourcesfor the observationofsecondary γγ production. Twosymmetricelectronbeams,generatedbyphotocathodes and acceleratedinlinacs,producetwoprimarygammaraysthroughComptonbackscatteringwithtwo high energylasers.Tuningthesystemenergytotheenergyofthephoton–photoncrosssectionmax- imum, a flux ofsecondarygammaphotonsisgenerated.Theprocessisanalyzedbystart-to-endsimu- lations fromthephotocathodestothepropagationoftheQEDphotonstowardsthedetector.Thenew Monte Carlocode ‘Rate OfScatteringEvents’ (ROSE)hasbeendeveloped ad hoc for thecountingofthe QED events.Realisticnumbersofthesecondarygammayield,referringtoexistingorapprovedset-ups and adiscussionofthefeasibilityoftheexperimentarepresented.
