Figure 3
An `undulator', a series of magnets of period P in the longitudinal direction, which forces the electrons to oscillate in a transverse direction (Margaritondo, 1988, 2002; Winick, 1995; Willmott, 2011; Mobilio et al., 2015; Bordovitsyn, 1999). Our relativistic description of the consequent undulator emission uses the reference frames R (laboratory and undulator) and R′ (electron). |
