Two new identical insertion devices have been designed for the Daresbury SRS. They are 2 T permanent‐magnet multipole wigglers that will provide high flux in the X‐ray region. This paper describes the magnetic and mechanical design of the arrays of steel pole pieces and permanent‐magnet blocks. Also given is the engineering design of the support structure that will cope with the very large forces present while maintaining high levels of precision in gap setting and parallelism. The engineering design has been fully assessed using finite‐element techniques to predict the deflections of critical parts of the structure. These two devices are due to be installed into the SRS by the end of 1998.
