The next generation of fusion experiments will operate for much longer pulse lengths, introducing several new requirements for diagnostics compared to existing experiments. With the installation of its upgrade named CIEL (a French acronym for internal components and limiter), Tore Supra has now to take into account most of these requirements, which can be developed in two parts. The first part deals with the thermal load on diagnostic components, and the need to optimise the geometry and develop specific protections with active cooling. The second set of requirements concerns the need for more complex control loops in order to maintain optimised modes of plasma operation for longer periods. This requires higher reliability and stability of calibration of the relevant diagnostics. There are also increased requirements for real-time data analysis and on-line displays to keep physicists informed of the state of the experiment and for intelligent systems to warn operators of potential dangerous plasma conditions. These and other requirements, and the way they are being dealt with on Tore Supra are presented.
