We describe the experiment designed by the FOR2783 research collaboration [1] to probe the single-step pair-creation process for the first time at the ATLAS laser at CALA. In the experiment, a high-energy bremsstrahlung γ-ray, produced using a 2.5 GeV monoenergetic electron beam with a charge of 10 pC, collides with a laser beam of intensity 9.5 x 1021 W/cm² (a0 = 66), triggering the pair creation process.
The created pairs are detected by a single-particle detection system composed of LYSO:Ce tracking layers and a Cherenkov calorimeter. GEANT4 Monte-Carlo simulations of the full experiment and expected pair yields are presented.
