Description
Betatron radiation generated by relativistic electrons oscillating in plasma wakefields constitutes a powerful, non-invasive diagnostic for both electron beams and the emitted photon radiation in plasma accelerators.
The spectral, angular, and statistical features of the radiation encode key information about electron dynamics, enabling single-shot reconstruction of electron beam parameters, such as oscillation amplitude, divergence, and normalized emittance.
In addition, recent studies have shown that shot-noise-induced spectral fluctuations in betatron radiation provide direct access to the temporal structure of the emitted XUV pulses, allowing single-shot, femtosecond-scale electron and photon diagnostics.
Complementary experimental and modeling efforts further demonstrate how detailed analysis of betatron spectra and angular distributions can be exploited to characterize both the electron phase space and the lateral coherence of the emitted radiation.
Together, these results establish betatron radiation as a versatile diagnostic tool that simultaneously probes electron and photon beam quality in plasma-based acceleration schemes.
