| − | * The electron detector is placed 5 mm above the primary electron beam. To check that, I forced the energy of the scattered electrons to be the one of the primary beam (E=1.165 GeV). The figure below demonstrates that the electron detector is effectively located above the primary beam (ignore the photon detector and scattered photons). | + | * [[Patricia]] |
