Abstract :
Several issues related to the engineering of permanent magnet undulators and wigglers are addressed. Shimming performs the correction of the integrated multipole components and provides a high brilliance on high harmonic numbers of the radiation spectrum. A design of termination is given which allows the removal of any electromagnet correction on hybrid wigglers. Another design of termination is presented which allows the phasing of two pure permanent magnet undulators at any gap value. Finally, some magnetic designs are presented which allow a high magnetic field for a short or medium spatial period
