PXR from Nonrelativistic Electrons

Abstract

The observation of parametric X-ray radiation (PXR) from ultrarelativistic electrons with energy E ≥ 50 MeV, considered in the preceding chapters, requires the use of linear particle accelerators, which usually have a low current J ≤ 10^-7 A. The PXR experiments at accelerator facilities are of interest for studying the fundamental features of the phenomenon and also for several specific applications. Despite high spectral density of PXR from ultrarelativistic electrons, the parametric X-rays, being used as an X-ray source, cannot compete with modern synchrotron sources utilizing the storage rings with a J ≃ 1-10 A [13].
