| Abstract: | The influence of a constant magnetic field on the radiation of a planar undulator is studied analytically with the use of
generalized Bessel functions. The behavior of on-axis radiation intensity in the undulator and the influence of a magnetic
field on off-axis radiation are investigated. The critical magnitude of the constant component of the magnetic field, which
has a significant effect on the motion of electrons in the undulator, is calculated analytically. The examples of several
planar undulators are discussed, and the influence of the Earth’s magnetic field on their spectrum is evaluated. |
