| Description | Journal: Plasma Physics A new method based on the laser-induced fluorescence method has been developed to measure the spatial electron density distribution in plasmas. The local electron density can be determined by observing the intensity ratio of the laser- to the collision-induced fluorescence. A spatial electron density distribution of a helium plasma $(T_{e}$ approximately 6 eV, n_{e}$:10^{11-12}$ $cm^{-3}$) has been determined by observing the $He(3^{1}$P to $2^{1}$S) laser-induced fluorescence and the $He(3^{1}$D to $2^{1}$P) collision-induced fluorescence resulting from the $He(3^{1}$P to $3^{1}$D) process due to collisions with electrons. The comparison of the result with that of a conventional method proves this new method is of practical use in the space-resolved measurements of plasma electron density. |
