Figure 1
Peak power as a function of propagation distance in the undulator with different initial energy spread. SASE and prebunched cases are compared here. SASE (ES = 0.05%) means FEL radiation generated from electrons with an energy spread of 0.05%; PreBunch (IB = 0.1) means FEL radiation generated from prebunched electrons with an initial bunching factor of 0.1.
