How do we establish sustainable early-stage SASE lasing in the storage ring?
The key to establishing sustainable early-stage SASE lasing in the storage ring is to cut ofthe lasing process at a relatively low power level before the electron beam quality degrades, and hence the electron beam is main- tained in an equilibrium state that supports turn-by-turn lasing.
What is the vertical emittance of a storage ring?
In practice, the vertical emittance is dominated by magnet alignment errors. Storage rings typically operate with a vertical emittance that is of order 1% of the horizontal emittance, but many can achieve emittance ratios somewhat smaller than this. ∗T. Raubenheimer, SLAC Report 387, p.19 ().
What is the equilibrium vertical emittance of a storage ring?
In many storage rings, the vertical dispersion in the absence of alignment, steering and coupling errors is zero, so Hy = 0. However, the equilibrium vertical emittance is larger than zero, because the vertical opening angle of the radiation excites some vertical betatron oscillations. 13 Cq βy εy = I ds.
Beam dynamics in a storage ring with a free-electron laser
The FEL lasing in the bypass line will increase the electron beam energy spread preventing it from lasing continuously. Therefore, after lasing in the bypass line, the electron beam will circulate in
