Abstract

Long living stationary multi faceted radiation from the edge (MARFEs) have been produced in TEXTOR-94 by gas puff feed-back controlled via the impurity radiation (CII line emission) from the MARFE zone. The stabilization of the MARFE opened a possibility to investigate this phenomenon in detail on a longer time scale. The population densities of excited state of deuterium in the MARFE were estimated from Balmer series line emission. The spectrum of the continuum radiation from the MARFE core has been measured in the spectral range 450-740 nm. The plasma parameters T_e = 1.1-1.5 eV and n_e = 2×10²⁰-2.1×10²⁰ m^-3 have been estimated from the measurements of the Balmer line emission, Balmer line Stark broadening and continuum radiation.
