Undulator magnet, undulator, and radiation light generating device
Abstract:
An undulator magnet having favorable transportation workability is provided. Specifically, an undulator permanent magnet used for an undulator is provided that generates radiation light by meandering electrons that travel in a first direction, wherein, in the undulator permanent magnet, one end surface in the first direction forms a first connecting surface connected to another undulator permanent magnet, N poles and S poles are alternately arranged in the first direction on one magnetic pole surface in a second direction orthogonal to the first direction, and thus a magnetic flux density distribution having a plurality of peaks is generated, and when the plurality of peaks are represented as the first to m-th peaks Pm (m is an integer of 1 or more) in order from the side of the first connecting surface, a magnitude of the first peak P1 is larger than a magnitude of the third peak P3.
