AB  - We describe a laser-plasma platform for photon-photon collisionexperiments to measure fundamental quantum electrodynamic processes such as thelinear Breit-Wheeler process with real photons. The platform has been developed usingthe Gemini laser facility at the Rutherford Appleton Laboratory. A laser wakefieldaccelerator and a bremsstrahlung convertor are used to generate a collimated beamof photons with energies of hundreds of MeV, that collide with keV x-ray photonsgenerated by a laser heated plasma target. To detect the pairs generated by the photonphoton collisions, a magnetic transport system has been developed which directsthe pairs onto scintillation-based and hybrid silicon pixel single particle detectors. We present commissioning results from an experimental campaign using this laserplasma platform for photon-photon physics, demonstrating successful generation ofboth photon sources, characterisation of the magnetic transport system and calibrationof the single particle detectors, and discuss the feasibility of this platform for theobservation of the Breit-Wheeler process. The design of the platform will also serve asthe basis for the investigation of strong-field quantum electrodynamic processes suchas the nonlinear Breit-Wheeler and the Trident process, or eventually, photon-photonscattering.
