Description
Inverse Compton scattering (ICS) is today a well-established route to produce tunable, high-brilliance photon beams for photon science, nuclear physics and fundamental studies. Pushing ICS sources towards higher photon energies requires electron beams in an energy range that only large-scale accelerator facilities can provide. Future linear colliders offer electron beams with energies extending from hundreds of GeV to the TeV scale, opening opportunities beyond their primary role as particle colliders. This activity is developed in natural synergy with analogous studies already carried out and ongoing for circular colliders, in particular the FCC-ee. We explore the use of these beams to generate high-energy photon radiation through inverse Compton scattering. As a benchmark, the LCF380 scenario with 190 GeV electrons is considered, using laser pulses synchronized with the electron bunches to provide the photon target for Compton interactions. The photon spectrum, yield, angular distribution and flux are studied as a function of the electron-beam and laser parameters. The study investigates the potential for producing intense and energetic photon beams, as well as possible configurations with multiple Compton interaction points along the linear accelerator. Finally, the scaling of the concept towards TeV-class linear colliders and its potential applications in photon science, nuclear physics and high-energy photon physics are discussed.
