Reduction of dynamic aperture encountered in 4th generation light sources presents a challenge for injection efficiency and commissioning. It’s possible that only after BBA and optics corrections are applied, will the dynamic aperture be sufficient for reasonable injection efficiency. Furthermore, it’s only after a circulating beam is established that BBA, BPM calibration, and other optics...
The next generation of light sources aim to provide bunch beams with small transverse emittances. A common feature in the design of light sources with small emittance lattices is the small value of the momentum compaction, which implies a short nominal equilibrium bunch length. Combined with the small transverse emittances, a short bunch length can pose severe limitations on the beam lifetime...
A method using transverse wigglers has been proposed for imparting arbitrary correlation on the transverse phase space. This concept employs transverse wigglers to introduce cosine-like modulations on the phase space. Similar to the approximation of periodic function by Fourier series, the series of properly designed cosine modulations approximates arbitrary correlations. Currently,...
