  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.

  Danfysik has delivered a full-energy turn-key injection system for the Australian Synchrotron. The system consists of a 100 MeV linac, a low-energy transfer beamline, a 130 m circumference 3-GeV booster, and a high energy transfer beamline. The booster lattice was designed to have many cells with combined-function magnets (dipole, quadrupole and sextupole fields) in order to reach a very small emittance. The injection system has been commissioned and found to deliver a beam with an emittance of less than 30 nm, and currents in single- and multi-bunch mode in excess of 0.5 and 5 mA, respectively, fulfilling the contractual performance specifications. The repetition frequency is 1 Hz. Results from the commissioning of the system will be presented.
