Simulation of ceramic windows for the APT/LEDA CCDTL
Development of a robust, high-average-power (up to 1 MW, CW) micro-wave transmission line system for the Accelerator Production of Tritium (APT) linac (linear accelerator) facility is a stringent engineering and operational requirement. One key component in this RF transmission system is the vacuum barrier window. The requirement of high-power handling capability coupled to the desirability of low probability of failure over lengthy time scales can be treated substantially with a set of microwave, thermomechanical, and Weibull analysis codes. This paper examines engineering models of ceramic windows for the Coupled-Cavity Drift-Tube Linac (CCDTL) segment of the APT Normal Conducting (NC) linac. The detailed cooling circuit is modeled and accurate heat deposition models for the RF are implemented. This simulation is then used to analyze the thermomechanically induced stresses on the CCDTL window configuration. A Weibull-distribution failure prediction code is used to integrate experimentally obtained ceramic material failure data and structural analysis calculations to infer reliability of the structure.
