Figure 13
The ratio = as a function of , for an electron energy spread of 0.5% (circles) and 1.5% (squares) and for a selection angle of 1 mrad (open symbols) and 2 mrad (full symbols). (a) bw = 0.1%. (b) bw = 0.7%. (c) bw = 3%. Lines are the analytic calculations (see text), points are CAIN simulations (the error bars are too small to be visible). |
