Abstract :
The direct imaging capacity of a triple-grating spectrometer designed for Thomson scattering is used for a cartographic study of the end of the column created by intermediate-pressure surfatron plasmas in argon. It is shown that the electron density decreases abruptly at the very end of the column. This effect is more pronounced for higher pressures and accompanied by a large rise in electron temperature.
