Electron beam dynamics studies during commissioning of the diamond storage ring

The Diamond Light Source is the new medium energy 3^rd generation light source located at the Harwell Science and Innovation Campus in the UK. The storage ring was successfully commissioned at full energy during the period Sept. to Dec. 2006, and is now delivering synchrotron light to users. During the commissioning period, operation of the storage ring at the design specifications was established in terms of closed orbit distortion, linear optics, coupling correction and emittance. In this report we provide details of these studies as well as more recent investigations into the zero- dispersion lattice.
