Insertion devices at the Swiss Light Source (phase I)

The insertion devices under construction for phase I of the Swiss Light Source (SLS) are described. Five undulators and one wiggler will be installed in four straight sections of the third generation 2.4 GeV SLS storage ring, under construction at the Paul Scherrer Institute. To provide undulator radiation in the energy range from 10 eV to 18 keV, both long period and short period, small gap undulators will be installed. (C) 2001 Elsevier Science B.V. All rights reserved.
