Abstract :
Compact light sources are being proposed for protein crystallography, medical imaging, nano-machining and other areas of study that require intense sources of X-rays at energies up to 35 keV. In order for a synchrotron light source to be attractive, its capital cost must be kept low. The proposed compact light source has superconducting bending elements to bend the stored beam and produce the X-rays. Additional focusing for the machine is provided by conventional quadrupoles. An important part of the cost optimization of a compact light source is the cost of the bending magnets. In the case of a machine with superconducting bending elements, the bending magnet system can represent close to half of the storage ring cost. The compact light source storage rings studied here have a range of stored electron energies from 1.0 to 1.5 GeV, For a number of reasons, it is desirable to keep the storage ring circumference below 30 meters. Cost optimization parameters include: (1) the number of superconducting bending elements in the ring, and (2) the central induction of the dipole. A machine design that features two superconducting dipoles in a single cryostat vacuum vessel is also discussed
