The tuning of the cavity options for DIAMOND

The RF group is considering both normally conducting and superconducting cavity systems for DIAMOND. This paper will discuss using temperature and longitudinal deformation as methods of tuning for a normally conducting cavity. The longitudinal deformation of a superconducting cavity is also discussed with its added technical difficulties of nanometer resolution and its cryogenic environment. A finite element analysis and URMEL-T software has been used extensively to predict cavity geometry changes and the associated frequency shift.
