Abstract:
A laminated wiggler, comprising:a plurality of permanent magnet lamina segments defining a cavity are stacked adjacent to one another along an axis such that they produce a periodically alternating magnetic field, having a sinusoidal field distribution along said axis, being transverse to said axis; a given one of the plurality of permanent magnet segments having a magnetic orientation the same as the magnetic orientation of at least one permanent magnet segment positioned immediately adjacent to said given one of the plurality of permanent magnet segments; an electron, passing along said axis, having a repetitive motion within said cavity caused by said sinusoidal field distribution, radiates with the frequency of a period of said periodically alternating magnetic field; and said sinusoidal field distribution reducing a plurality of harmonics generated by an abrupt magnetic field reversal from one of said plurality of permanent magnet segments to another of said plurality of permanent magnet segments, whereby said electron is accelerated and produces an enhanced coherent monotonic light emission.
