Water layer and radiation damage effects on the orientation recovery of proteins in single-particle imaging at an X-ray free-electron laser

open access: yesScientific Reports, 2023
The noise caused by sample heterogeneity (including sample solvent) has been identified as one of the determinant factors for a successful X-ray single-particle imaging experiment.

Nonintercepting electron beam size monitor using optical diffraction radiation interference

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2011
In recent years, the use of diffraction radiation (DR), emitted when a charged particle beam passes through a rectangular slit, has been proposed and successfully tested as a nonintercepting diagnostic of high brightness beams.

On the problem of application of diffracted transition radiation for indication of relativistic electron beam parameters [PDF]

open access: yesJournal of Instrumentation, 2020
The diffracted transition radiation (DTR) produced by a beam of relativistic electrons traversing a thin single-crystal plate in the Laue scattering geometry is considered. We have obtained the expression describing the angular density of the DTR for the case when the path length of the electron in the target is far less than the extinction length of X-
