Abstract

A new setup for the measurement of electron channeling radiation has been taken into operation at the ELBE radiation source. First experiments at electron energies of 14.6 and 17 MeV using diamond type-IIa crystals were aimed at the verification of the dependence of the yield of channeling radiation on the crystal thickness. While the dissipative approach assuming an exponentially decreasing occupation function with an energy-dependent characteristic occupation length (l_occ) is able to describe the yield up to a thickness of about 2l_occ multiple scattering remarkable influences the yield at larger crystal thickness.
