Query: Simulation study of betatron radiation in AWAKE Run 2 experiment   The spectroscopy of betatron radiation from the focusing plasma column can
work as a powerful non-invasive beam diagnostic method for plasma wakefield
acceleration experiments such as the AWAKE. In this paper, the effects of
radial size mismatch and off-axis injection on the beam dynamics, as well as
the spectral features of the betatron radiation emitted by the witness electron
bunch in the quasi-linear proton-driven plasma wakefield are studied. It is
shown that the evolution of the critical betatron photon energy and the overall
photon angular distribution can effectively reveal the initial injection
conditions of the witness electron bunch. The possibility of using this method
for the diagnostics of the seed electron bunch in the proton self-modulation
stage of AWAKE Run 2 is also discussed.
