Abstract
A method of variation of the undulator radiation wavelength is conside red. The method is based on the influence of the undulator magnetic fi eld shape on the radiation frequency. It has been shown that the chang e of the partial contribution of higher harmonics (mainly of the third harmonic) into the magnetic field shape leads to smooth tuning of the radiation frequency within a range adequate to three-fold changes of the undulator period. An undulator scheme providing such properties wi thout reconstruction of the undulator design has been proposed. (C) 19 98 Elsevier Science B.V. All rights reserved.
