RADIATION SPECTRA OF 200 MEV ELECTRONS IN DIAMOND AND SILICON CRYSTALS AT AXIAL AND PLANAR ORIENTATIONS
This work is supported by Swedish Research Council, the Craaford Foundation, the Wennergren Foundation, the Royal Physiographic Society in Lund and the Knut and Alice Wallenberg Foundation, by the European Community – Research Infrastructure Action under the FP6 "Structuring the European Research Area" Programme (through the Integrated Infrastructure Initiative "Hadron Physics") and partly supported by STCU project 3239.
Results of the first experiment on studying the radiation spectra of electrons with energy 192 7 MeV in diamond and silicon crystals at axial and plane orientation performed at the MAX-lab facility were presented. At these orientation the particle's motion can be both regular, when axial and planar channeling are possible, and chaotic, when the coherent electron interaction with single strings reveals itself. Essential increase of the radiation intensity at low photon energy region, less than 15 MeV, is observed.
