Description
Achieving higher spectral brightness in fourth-generation light sources like the Southern Advanced Photon Source (SAPS) through integrated free-electron laser (FEL) oscillators presents significant challenges. In response, we present a systematic optimization of the parameters for a low-gain FEL oscillator on the SAPS storage ring. Our work quantitatively evaluates how a transverse gradient undulator (TGU) modifies the ring's equilibrium beam parameters and analyzes the effects of harmonic operation and undulator length on FEL gain. These findings offer essential design guidance for implementing such FEL oscillators in storage rings.
