Abstract

We present the test results of a novel microwiggler structure [1] for free-electron lasers, in which, each 2.4 mm period consists of two channels of miniature electro magnets energized by current with opposite polarities. The magnetic field in each half-period is independently controllable and the tunability is demonstrated experimentally, which may provide means for reducing random field errors; for field tapering; for optical klystron configurations; and for electron beam injection.
