We present a detailed derivation of a formula for the small-gain calculation for an x-ray free electron laser oscillator (XFELO) based on a medium-energy (3–4 GeV) storage ring. We found harmonic lasing and strong focusing are essential for this beam energy range.

Abstract We revisit free-electron laser (FEL) equations in the presence of a planar undulator to investigate effects on longitudinal FEL dynamics upon seeding by a harmonic. For this study, we adopt slowly varying phase approximation, collective variables, and Klimontovich description of particle beams to explore the effects of harmonic seeding on low-gain saturation, low-gain amplification, and exponential growth for on-axis radiation emission.

Warehouse construction time lapse monitoring services are similar to general time lapse services, but they focus specifically on capturing and documenting the construction process of a warehouse facility. These services provide a visual record of the entire construction project, from start to finish, by capturing images or videos at regular intervals.
