Abstract
A nitrogen plasma was created in an electromagnetically driven T tube. Electron density was determined by the laser interferometry at two different wavelengths while electron temperature .from relative intensities of N II lines. Electron density varied from 3.09 to 4.84 · 10^17 cm^-3, electron temperature from 16200 to 18300 °K. The profiles of various lines emitted in the plasma were obtained by scanning with a monochromator from shot to shot. Half widths of nitrogen ion lines were measured from the impact broadened profiles and compared with the theory and other experimental results.
