Abstract:An overview of the design of the undulator for the Twente free electron laser is presented. The undulator is of the planar hybrid type, i.e. alternating permanent magnetic material and poles. The overall design is based on the method of Halbach. The flux balance is set up for the three-dimensional fluxes which are derived from the two-dimensional calculations. The undulator, using magnetic materials Sm1Co5 and 2V-permendur, has a wavelength of 25 mm, K value of 1, and a betatron wavelength (at equal focusing) of 300 mm for an electron beam of 6 MeV. An optimization is performed on a circular shape of the pole faces. The entrance and exit are tapered to allow a straight passage of the electron beam through the undulator. The tapering is adjusted to the requirements of minimal steering and displacement of the electron beam.
