An intense channeling radiation source

A nonconventional x-ray source based on the production of electron channeling radiation in a diamond crystal has been installed at the Radiation source ELBE. The brilliant electron beam with an average current up to 100 microA available in the radiation physics cave allows to reach photon rates of quasi-monochromatic channeling radiation of the order of 10^(11) s^(-1) per 10% bandwidth. On-line x-ray monitoring was realised using a Compton spectrometer. The photon energy can be tuned by variation of the beam energy. Monochromisation of channeling radiation and bremsstrahlung background reduction have been investigated applying x-ray diffraction on a HOPG crystal.
