  Danfysik A/S* has recently designed and produced a high-performance Apple-II type insertion device for the Australian Synchrotron Project, with low variation of the first integrals versus gap and phase, and minimal phase error. Thanks to software assistance, and an unconventional keeper design, the total time spent on magnet mounting, shimming and final magnetic testing was reduced to 5 weeks. Furthermore, in order to negate the second-order tune effect of the insertion device on the dynamic aperture, ESRF-type tune shims were designed and installed. Danfysik is manufacturing and assembling one of three undulator prototypes for the TESLA FEL project at DESY. The prototype is based on a design made by DESY, but with changes implemented by Danfysik. A major part of the project is to make an industrial study that will recommend where design efforts on the next prototype generation shall be focused.
