A progress report about 15 years molecular spectroscopy on TEXTOR is given. Spectra of CH/H, BH/D, SiH/D, C 2 , CO and H 2 /D 2 are discussed for plasma boundary conditions in a fusion device and the behaviour of these constituents for varying plasma

In TEXTOR-94 experiments have been performed which try to elucidate the nature and origin of the hydrogen released from plasma facing graphite surfaces. Density profiles and velocity distributions have been measured by means of passive and active spe

Characteristic quantities for impurity release from limiters and the penetration of atoms into the plasma boundary have been determined by optical methods on the tokamak TEXTOR-94. The velocity distribution of neon atoms released from a tungsten limi

Profiles of the Balmer lines D α (H α ), D β (H β ) and D γ (H γ ) have been measured in the scrape-off layer and within the edge of the TEXTOR (upgrade) plasma, under Ohmic conditions and with neutral-beam injection. Each line profile shows a

The velocity distribution of neon atoms recycling at a carbon limiter has been determined from the Doppler broadening of a NeI line at λ = 585.248 nm (3s′[1/2]J=1−3p′[1/2]J=0). The measured velocity distribution matches well the radial intensi

In the beam heated (1.3 MW) plasma of the TEXTOR tokamak, ion temperatures T i between 30 and 120 eV have been measured in front of a test limiter at line averaged electron densities between 4 × 10 13 and 1.5 × 10 13 cm −3 . The Doppler broadened

Experimental results from TEXTOR are presented to provide strong evidence for the feasibility of the 'cold radiative plasma mantle', a concept which might be a possible solution for the energy exhaust problem in a fusion reactor. The concept is compa

Plasma‐wall interaction and impurity transport processes in the outermost region of magnetically confined hot plasmas (the so‐called plasma edge) must be well understood for successful development of future thermonuclear fusion reactors. To this

From the Doppler-broadened emission profiles of a CI line (3P2→3P20, λ=909.5 nm) and of an OI line (3P2,1,0→3S10, λ=844.6 nm), the velocity distribution of carbon and oxygen atoms in front of a graphite limiter has been deduced. For the π-comp
