Fig. 10: EOS temporal measurements and computed spectra as function of beam energy.
From: Towards higher frequencies in a compact prebunched waveguide THz-FEL
a Ebeam arrival inferred from simulation. b Data traces are plotted over the start-to-end simulation results from GPT-FEL. The dotted lines show the phase resonances from the analytical theory. Inlay shows tunability of the central peak in the high frequency branch and the associated rms spectral bandwidth (white) over theory (black).
