Figure 1
The magnetic model of an Apple X generated by the RADIA code (Chubar et al., 1998BB6). The longitudinal position of each row is represented by the variable ϕn = 0, at its initial position (before the change of variable) which generates an identical zero field on-axis. There are four different directions of magnetization, represented by four colors, where one set forms a single undulator period λu.
