In this contribution, we present an exploratory study of the radiation expected to be produced during plasma wakefield acceleration (PWFA) of electrons.
Understanding radiation in the IR to UV range is key to diagnosing the responsible plasma processes in future PWFA accelerators. One goal of the study is to identify radiation signatures suitable for controlling beam quality, thereby enabling high-brightness electron beams for future applications.
The data for our analysis is obtained from PWFA simulations with the 3D3V particle-in-cell code PIConGPU. Emissions are computed using electromagnetic fields derived from Liénard-Wiechert potentials for the entirety of the simulated particles, thereby enabling analysis of the influence of collective plasma dynamics on the observed radiation and allowing quantitative predictions of signal-to-noise ratios. Furthermore, the capability of PIConGPU to select specific groups of radiating particles allows us to determine the origin of spectral signatures.
