A Proposed Lattice Modification to the Daresbury SRS

The Synchrotron Radiation Source (SRS) at Daresbury was the world's first purpose built x-ray source dedicated to synchrotron radiation experiments. Since the SRS was designed much further work has been carried out on the optimisation of radiation sources, and this has led to the realisation of the importance of source brightness. Accordingly a proposal has been made to upgrade the SRS by increasing the periodicity through the addition of further quadrupoles, in order to reduce the emittance of the stored electron beam by an order of magnitude. The practical implications of this change are discussed. Approval for this project is being sought.
