Coherent bremsstrahlung in crystals as a tool for producing high energy photon beams to be used in photoproduction experiments at CERN SPS

Abstract

We recall the properties of coherent bremsstrahlung of high energy electrons in single crystals and show that a suitably oriented diamond crystal can produce a high energy bremsstrahlung beam whose quasimonochromatic spectral composition may be exploited for increasing the production rate in a photoproduction experiment at hundreds of GeV. A careful analysis of the required angular resolutions is performed. It turns out that the standard deviation of the electron beam angular divergence in one plane should be less than 0.3 mrad, for a beam energy of 150 GeV. The standard deviation in the perpendicular plane is not critical. In this situation the photoproduction rate in a typical case is increased by a factor of about 3 with respect to the conventional bremsstrahlung beam.
