Time duration of the parametric x-ray radiation

TL;DR

This paper investigates the time evolution of parametric X-Ray radiation produced by relativistic particles in crystals, highlighting its long duration which enables detailed experimental analysis of its complex temporal structure.

Contribution

It introduces the study of long-duration parametric X-ray radiation, allowing for detailed time-structure investigations using modern accelerator facilities.

Findings

Parametric X-ray radiation can last around 0.1 ns, much longer than the particle flight time.

Longer radiation duration enables detailed temporal analysis of X-ray pulses.

Potential for new experimental insights into X-ray pulse structures.

Abstract

Time evolution of the parametric X-Ray radiation, produced by a relativistic charged particle passing through a crystal, is studied. The most attention is given to the cases when the radiation lasts much longer (t_{PXR} ~0.1 ns) than the the time t_p of the particle flight through the crystal (t_p ~ 1 ps). It is shown that such long duration of the radiation makes possible the detailed experimental investigation of the complicated time structure of the parametric X-ray pulses, generated by electron bunches, which are available with modern acceleration facilities.
