Abstract:

We have designed, built, tested, and operated a 70-period electromagnet planar microwiggler for use in free electron laser FELs, constructed of current conductors wound on ferromagnetic cores. The device has an 8.8 mm period and a 4.2 mm gap and produces 0.5-msec magnetic field pulses of 4.0 kG at a rate of 12 Hz. The field of each half-period of the wiggler is independently adjustable we have developed a novel tuning regimen and employed it to reduce the RMS spread in peak amplitude of a uniform field profile to 0. 12, the best of any sub-cm period wiggler of which we are aware. In addition, the field at the ends of the wiggler have been tapered for reduced electron-beam steering and deflection
