The Amsterdam pulse stretcher AmPS as a photon source

AmPS, an electron Pulse Stretcher/Storage Ring will start delivering nearly continuous electron beams of maximum 900 MeV in Spring 1992. The extracted beam (using the machine in Stretcher Mode) as well as the stored beam (in conjunction with an internal gas-jet target) will be used for nuclear physics purposes for about 2500 hours/year. For the remaining time of the year AmPS could be used as a dedicated Photon Source covering the spectrum from infrared up to soft X-rays. The synchrotron radiation properties of the actual machine are presented together with a design for a modified ring lattice. Enhancement of the brilliance can be achieved by the implementation of multipole undulators. (author) 3 refs.; 3 figs.; 3 tabs
