The data acquisition system for the infrared cameras on Tore Supra

The data acquisition for the infrared measurement system on Tore-Supra is a key element to ensure the supervision of the new actively cooled plasma-facing components of CIEL (Inner Components and Limiter), which is a major upgrade of Tore Supra. It will allow us to follow the thermal evolution of components of Tore-Supra, in particular the toroidal pumped limiter (LPT) (360/spl deg/-15 m long) and the five additional heating launchers. When fully installed, the infrared measurement system will be composed of 12 digital 14-bit infrared cameras. They cover a 100-1200/spl deg/C temperature range, and each picture has a definition of 320 /spl times/ 240 pixels with a 20 ms time resolution. The objectives of the data acquisition system are real-time recording and analysis of each view element for further postpulse analysis in order to understand the physics phenomenon and ensure the supervision of the plasma facing components, and also to be part of the global feedback control system of Tore Supra.
