“…(37) agrees very well with experiments when CPR is observed in the Laue geometry: for example, see Brenzinger et al (1997). However, it has been said that some peculiarities may exist under the Bragg geometry since Fiorito et al (1993) reported rather surprising enhancement using graphite target. Recently, Freudenberger et al (2000) published a paper entitled: ''Parametric X-rays observed under Bragg condition: boost of intensity by a factor of two''.…”

“…This is an extremely interesting question since it is of importance for the theoretical understanding of the interaction process. In the only other existing Bragg case experiment [17] the observed intensity was larger than predicted and increased with increasing reciprocal lattice vector g of the crystal. There was no theoretical explanation of this observation, which is a further motivation of the present work to check this result independently.…”

“…An increasing number of photons with increasing reciprocal lattice vector has not been observed. The effect reported by [17]-especially for graphite but also for silicon-could thus not be reproduced.…”

Parametric x rays (PXR) produced by bombarding silicon and diamond crystals with electrons of 30 to 87 MeV were detected at 180 degrees relative to the direction of the electron beam. It was found that the dependence of the intensity on the orientation of the crystal agrees with the predictions of the kinematical theory of PXR. The absolute intensity is twice as large as predicted. These findings can be explained considering dynamical effects that govern the x-ray crystal interaction. Additionally, x rays caused by self-diffracted transition radiation have been observed.

We present measurements of x-ray emission from relativistic electrons passing through crystals and multilayer nanostructures mounted inside betatrons. Both spectra and yields have been measured. The measured spatial distributions and orientation dependencies are presented and are found to be in good agreement with theory. Betatrons developed over the past 30 years in Russia are compact and relatively inexpensive compared to LINACs and Storage Rings, and thus can be used in small laboratory settings. Various thin novel radiators mounted inside the betatron toroid can be used to generate (1) monochromatic tunable x-rays from crystalline and multilayer targets (2) tailored γ-ray emission spectra from single thin foils and (3) soft x-ray spectra from multiple thin foils (transition radiation). Although betatrons have relatively low current, the thin radiators permit the multipassing of the electron beam for increased efficiency.
