Description
On the Thomson scattering of Tore Supra a systematic study of the noise was carried out in order to take measures to upgrade the system and to give a polychromator prototype benefit from that. In this paper, we discuss: a description of the various noises observed in particular using a controllable fast oscilloscope remotely by network Intranet, the conclusions that we have derived for the prototype, acquisition and processing associated. The installation of fast acquisition and processing based on correlator should improve the signal to noise ratio of about 6 to 10 dB during plasma with strong additional heating and make disappear aberrant points.
