Abstract
A source to produce channeling radiation has been set up immediately behind the injector of the new superconducting electron accelerator, which has gone into operation this summer. The electron beam energy at that stage of the machine can be varied between 3 and 10 MeV and the low value for its divergence (0.041-0.015 mrad) is suited to create monoenergetic, polarized photons of high intensity in the keV-region. It is projected that an electron beam of 20 µ A and 10 MeV hitting a Si crystal produces a photon intensity of 1010 - 1011 photons/s into 1 mrad solid angle with a band width of Ɗ/E=0.1 at an energy of about 45 keV. The first crystals under investigation will be a Si (111) and a diamond (110) crystal.
