Abstract

Parametric x-ray radiation of type B has been produced with an electron beam of energies between 3.5 and 9.1 MeV from the superconducting accelerator S-DALINAC and diamond of thickness $55 μ m$ . The photon intensity and its energy dependence were determined as a function of the tilt angle of the crystal. The intensity maximum varies with $γ^{2}$ and is about 3 orders of magnitude smaller than channeling radiation. Comparison with theoretical predictions exhibits very good agreement after taking into account effects caused by multiple scattering of the electrons in the crystal.
