SOLEIL, a new synchrotron radiation source for LURE

LURE is designing a new storage ring of energy 2.15 GeV which will provide radiation in the intermediate energy range, 20 eV-1.5 keV, from undulators and 5 keV critical energy photons from dipole bends. On the basis of what was learned from Super-ACO experience, a number of criteria were retained for the new machine: large number of insertion sections (13), 3 and 5 m long, for a comparatively short circumference (216 m), moderate emittance (3.7 10^-8m.rad) to secure good Touschek lifetime for the operation with a few intense bunches and for a realistic energy acceptance. Particular attention is paid to all aspects leading to the stability of the photon beam. A decision is looked for 1993-94. The construction time should be 4 years.
