In fusionplasmas, for instance, reflection properties of the plasma facing mir-ror and plasma wall components have a strong impact on the signalin the visible range. Until now no technique exists, which is able tomonitor the modification of the optical properties without any addi-tional calibration sources. We present anin-situtechnique to measurethe reflectance, its dynamic evolution and the polarization of differentmetallic surfaces (e.g. C, Al, Ti, Fe, Mo, Rh, Pd, Ag, Sn and W) ina H/Ar mixed plasma. The measurements are performed in the lin-ear plasma device PSI-2, operating in the electron density range of1011−1012cm−3and electron temperature range of4−10eV. Theoptical properties are measured by analyzing the Doppler-shifted emis-sion of fast hydrogen atoms, backscattered from the metallic surface,at different lines-of-sight at656.279nm (Balmer-훼line). The compar-ison between measured reflectance and theoretical data shows a verygood agreement (within 10%).Part:PType:Vortrag;TalkTopic:Plasma-Oberflächen Wechselwirkung;Plasma Wall InteractionEmail:s.dickheuer@fz-juelich.de | ||
