Description
AWAKE is CERN's proton-driven plasma wakefield acceleration experiment, currently advancing toward Run-2c to demonstrate the higher energy acceleration of electrons while maintaining the beam quality. A second electron beam (of 150 MeV energy), produced in a newly installed electron source, will be injected and accelerated to several GeVs while aiming to keep good emittance. Diagnostics are being upgraded for this geometrically constrained injection-region to enable single-shot characterization of that beam, among which this contribution evaluates the feasibility of optical synchrotron radiation (OSR) as a non-invasive real-time mean.
OSR can provide shot-by-shot transverse position and profile information without disrupting beam delivery, critical for benchmarking beam-alignment and quality check. The prompt, non-invasive nature also makes it a candidate for future virtual diagnostic implementations, where online beam profiles could inform predictive models or feedback correction schemes.
For performance optimizations the expected OSR photon flux, photon statistics, projected image quality are computed with realistic imaging optics and detector quantum efficiency. Results demonstrate that sufficient OSR signal can be extracted through this compact optical chain to achieve meaningful single-shot transverse profile measurements.
