Summary:Design automation techniques are being, developed to facilitate the design of the normal conducting Coupled-Cavity Drift Tube LINAC (CCDTL) and Coupled-Cavity LINAC (CCL) for the Accelerator Production of Tritium (APT). The cavity geometry is generated from automated RF design codes and fed directly into a 3-D multiphysics code which calculates the RF heat loads and cavity distortions due to the heat loads. The resulting frequency change in the cavity is determined by the Slater perturbation formulation. Cooling is located to minimize these distortions. The application and their status as applied to the APT CCL will be discussed. In particular, the use of specific codes to reduce the peak thermal stress around the coupling slots in these cw (continuous wave) RF cavities will be presented.
