Enhancement of betatron X-ray radiation produced in laser–plasma accelerators has previously been achieved by increasing the transverse oscillation amplitude of accelerated electrons in a tilted-shock traversal. This article reports on a simultaneous analysis of the properties of the betatron radiation and the trajectories of the relativistic electrons. The correlations of their parameters indicate new opportunities for improving betatron sources.
Levine et al. (2026) studied this question.
