sentence: Electrons traversing the periodic magnet structure are forced to undergo oscillations.
sentences_before: It consists of a periodic structure of dipole magnets.
sentences_after: So the electrongs give off energy as electronmagnetic radiation. The radiation produced in an undulator is very intense and concentrated in narrow energy bands in the spectrum. The light beam is also collimated on the orbit plane of the electrons. This radiation is guided through beamlines for experiments in various scientific areas.
