The classical method of generating photon beams in the MeV range is based on the process of inverse Compton scattering of a laser light on electrons. The intensity of such beams will always be limited because the wavelength of the laser photons is sizably larger than the classical electron radius. In my talk, I shall argue that partially stripped ions can be employed as, by far, more efficient boosters of the frequency of the laser-photons than electrons. I shall discuss the feasibility of accelerating and storing beams of partially stripped ions in the LHC storage rings. I shall focus, in particular, on their potential to generate high intensity, MeV-range, photon beams at CERN. Such beams could open many new domains of basic research and applications, including gamma-proton and gamma-gamma collision physics, axion searches, photo-transmutation of nuclear isotopes, gamma-ray transmission radiography, cancer therapy and production of intensive beams of polarized positrons.
