In order to simulate the SEU response of devices in the CLEAR facility at CERN, there will be need to perform simulations of high-energy electron and photon beams.
Currently, these cannot be handled because the physics libraries including the relevant photonuclear and electronuclear processes, that are very important a tens and hundreds of MeV are not implemented within G4SEE. However, they should be available in Geant4 itself and can be implemented in G4SEE in the future.
