Canadian Light Source proposal

The storage ring for a 2.9 GeV Canadian Light Source has been designed. The lattice is composed of twelve compact DBA cells resulting in a ring that is 148 meters in circumference with twelve drifts of 4.5 meters for the inclusion of insertion devices. The emittance is less than 20 nm-rad, resulting in radiation brightness competitive with other "third generation" sources. Details of orbit correction, beam stability and lifetime and the effect of insertion devices have been investigated. The RF requirements have been defined and preliminary magnet designs have been done. The light source will operate with full energy injection and the injection scheme has been fully defined. Injection includes a 300 MeV linear accelerator, low energy transfer line, booster synchrotron and high energy transfer to the storage ring. With this configuration it will be possible to operate the storage ring with beam currents up to 500 mA, resulting in a source of very intense light over a broad range of photon energies. Far example, with a state of the art undulator, it will be possible to produce 20 keV photons with a brightness close to 10/sup 18/ photons/s/mm/sup 2//mrad/sup 2//0.1% bandwidth.
