Description
The transverse gradient undulator (TGU) is a key component for realizing diffraction-limited storage-ring-based X-ray free-electron laser oscillators (XFELOs), as it can compensate for the large energy spread in storage ring electron beams. Previous studies have mainly focused on the small-signal gain of the TGU in such a setup. However, under large-signal conditions, the gain can deviate significantly from the small-signal gain. In this contribution, we investigate the TGU gain in the large-signal regime using three-dimensional simulations. We also examine the effects of large-signal interaction on beam quality, in particular the increase in beam emittance.
