This is another volume in the excellent-value paperback series produced by the US society. The source material for the book was derived from lectures given at the workshop of the same title given in conjunction with the 11th International Clay Conference held in Ottawa, Canada in 1997.

Whenever charged particles are accelerated they emit electromagnetic radiation, and it has long been possible to obtain very intense fluxes of X-rays from synchrotrons. These are large machines into which electrons or their positively charged counterparts, positrons, are injected into a beam and then accelerated around ring-shaped paths to near the speed of light using bending magnets. However, these machines were built originally to perform high-energy physics experiments on the fundamental structure of matter, and the production of X-rays and other electromagnetic waves was regarded as merely junk, parasitic noise to be overcome. However, crystallographers eventually caught on to the fact that these machines could produce X-ray fluxes many orders of magnitude higher than the tubes of conventional laboratory diffractometers. One further major difference . . . [Full Text of this Article]
