XXXI International Conference on the Physics of Charged-Particle Interaction with Crystals (Institute of Nuclear Physics, Moscow State University, Moscow, May 28-30, 2001) Parametric X-Ray Radiation Generated by 5.7-MeV Electrons in a Pyrolytic-Graphite Crystal

Parametric x-ray radiation is observed in a mosaic pyrolytic-graphite crystal irradiated with a 5.7-MeV electron beam. The first-order (002) reflection of parametric x-ray radiation is detected in Bragg geometry. In the measured spectra, there is a peak at about 8 keV. The detector used is arranged at an angle of ΘD =2 Θ B =2 7 ◦ with respect to the electron beam, where ΘB is the Bragg angle. The target thickness is 0.3 mm. The spectra of parametric x-ray radiation are measured at various angles of target orientation with respect to the axis of the incident-electron beam. c � 2003 MAIK "Nauka/Interperiodica".
