Abstract

During the 1999 experimental Tore-Supra campaign, an unexpected high near infrared (NIR) emission was observed when looking at carbonaceous surfaces under the impact of plasma and high energy ions: a radiation different from blackbody. Such an extra luminance phenomenon has now been produced in controlled way in laboratory experiments. Here we report on measurements using a helicon plasma source at LPIIM, Marseille. As with previous experiments on Tore Supra, the laboratory observed NIR spectra are different from simple blackbody radiation curves under certain conditions. Luminescence phenomenon is discussed to explain extra luminance from carbon surfaces under plasma particles impact.
