Abstract

Daresbury Laboratory is involved in a collaboration with BESSY, DELTA, MAX-Lab and NTHU to develop a normally conducting 500 MHz accelerating cavity for electron storage rings with significantly damped high order modes (HOM´s). This paper describes some of the mechanical engineering challenges facing the project and suggest possible solutions. Finite element analysis using the high frequency electromagnetic module, in ANSYS has been used to calculate the thermal and structural stresses. These results have then been used to determine the cooling requirements during operation at 100 kW. Methods of fabrication have been evaluated with a view to minimising cost and complexity. A preliminary investigation into various tuning techniques has also been carried out
