The Canadian Light Source (CLS) is now under construction. It will be a third generation source capable of producing photon beams for a variety of research applications. The CLS has four principal components: a 250 MeV linac, a full energy booster, a storage ring, and an array of beam lines serving interests ranging from infrared light to hard X-rays. The 2.9 GeV storage ring has a compact design made up of twelve double bend achromats incorporating twelve 5 m straights for injection, RF and insertion devices (IDs). RF power for the storage ring will be supplied by a single superconducting cell operating at 500 MHz. Construction and commissioning should be complete by the end of 2003 and an initial complement of five IDs and three bend magnet sources supplying light to eight beam lines and eleven experimental end stations is anticipated. Photon beams with high brightness will be achieved through a combination of low electron beam emittance (18 nm-rad), high circulating current (500 mA), small vertical coupling and a variety of undulator magnets. The use of small gap undulators will result in bright beams at photon energies up to 20 keV. |
