Methodology for the design of diagnostic windows for Tore Supra

The next generation of fusion experiments will operate for much longer pulse lengths within a context of high power density, introducing several new requirements for diagnostics compared with existing experiments. In this context, the upgrade of Tore Supra (CIEL Project) foresees high power and high radiating plasma scenario during very long pulse operation. This long plasma operation imposes the improvement of diagnostic systems and the design of thermally resistant in-vessel components with reliable window assemblies. Hence, the specific requirements and the methodology adopted to design Tore Supra/CIEL (TS) high thermal loaded diagnostic windows are summarised in this paper. Thermal and mechanical analyses are reported for different window materials and assembling methods.
