ELECTROMAGNETIC DESIGN OF THE SLS SUPERCONDUCTING BENDING MAGNET WITHLINEAR GRADIENT

The Paul Scherrer Institute is studying a synchrotron radiation source , the Swiss Light Source, for a variety of applications in physics, ch emistry, material sciences and industrial production. Specially optimi zed superconducting bending magnets will provide the hard X-rays neces sary for structure analysis and micro-fabrication. This preliminary de sign study investigates a combined function magnet system with dipole and quadrupole coils, for bending and focusing of the electron beam. T he electromagnetic characteristics of the magnet, including the end ef fects, are studied in 2-D and 3-D analyses. The proposed concept is fe asible to satisfy the requirements of field strength and quality in th e envelope of specifications, white an optimization of the coil geomet ry is recommended to improve the longitudinal magnetic characteristics .
