Abstract :
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
