Abstrakt: The yield of parametric x-ray radiation from a tungsten single crystal irradiated with a E = 1500 MeV electron beam from the Tomsk Sirius synchrotron was studied experimentally in Bragg geometry. The tungsten sample was 1.7 mm thick and had a surface mosaicity less than 1.5'; it was oriented in such a way that the (111) face was at the Bragg angle of θ[sub B] = 45° with respect to the electron-beam direction. The x-ray photons were detected at the angle of 2θ[sub B] = 90° with respect to the electron beam. The angular distributions of parametric x rays are compared with those calculated with allowance for actual experimental conditions.
