The position is at “Laboratoire de Physique des 2 Infinis Irène Joliot-Curie” (IJCLab), in the Beam Instrumentation, Manipulation and Physics team (BIMP) of the Accelerator division of the laboratory.
The work will mainly involve the design and detailed simulation studies of the positron injector for the e+e- Future Circular Collider FCC-ee. The FCC-ee is a high-luminosity, high-precision circular collider to be constructed in a new 100 km tunnel in the Geneva area. It is part of the Future Circular Collider design study at CERN, and would be the first step towards the long-term goal of a 100 TeV proton-proton collider. The physics case is well established and the FCC-ee operation is foreseen at 91 GeV (Z-pole), 160 GeV (W pair production threshold), 240 GeV (Higgs resonance) and 350 GeV (t-tbar threshold). Positron injector is one of the key elements of the FCC-ee requiring special attention. Due to the large 6D production emittance and important thermal load in the production target, the positron source characteristics define many of the collider parameters.
