摘要
Beam loss due to charge exchange scattering leads to a fundamental limit for the acceptable storage time. Recently measured cross-sections for Bi1+ and Au1- are evaluated in a computer program, which takes into account the variation of beam temperature and density in the storage ring due to strong focusing. In particular we have found that in case of Bi1+ the loss is increasing with emittance, whereas for Au1- the behaviour is the opposite due to a different dependence of the ion cross-sections on collision energy. Examples are presented for driver storage rings. Several examples of synchrotrons for an experimental facility leading beyond the threshold of radiation conversion physics have been studied.
