The channeling radiation spectrum for electrons in the sub-GeV to several GeV range exhibits a broad peak at photon energies reaching several tens of MeV. This property makes it suitable for inducing (
, n) photonuclear reactions in a subsequent target. For a given radiator thickness, the flux of channeling radiation can surpass that of bremsstrahlung by over an order of magnitude. This high flux is highly effective for studying photonuclear reactions within the giant dipole resonance region and for producing pulsed neutron beams. Detailed yield calculations for neutrons from targets of Au, Pb, U, Zn, and Si reveal a complex dependence on both the incident electron beam’s energy and its alignment with the crystal’s channeling planes.
