Title MOPKF066 Magnetic Design of a Focusing Undulator for ALPHA-X
Abstract ALPHA-X is a four-year project shared between several research groups in the UK to build a laser-plasma accelerator and produce coherent short-wavelength radiation in an FEL. The FEL undulator will be a 1.5m long, 100 period permanent magnet device with a minimum gap of 5.5mm and a peak field of 0.7T. Horizontal and vertical focusing of the beam within the undulator is realised by the undulator’s block shape, which is designed to approximate a parabolic pole face. The magnetic design of the undulator is complete; design of the support structure is well under way. Test pieces have been built to ensure that the clamping arrangement is strong enough to cope with the magnetic forces involved (7.9kN between the two arrays). The complete undulator will be built in late 2004 at Daresbury Laboratory, and tested on-site in the new magnet test facility.
