We use a new method to measure electron density in the boundary layer of plasma, which is based on the fluorescence resulting from the collision of electron and lithium atom. We observe the fluorescence signal of lithium atom at 6708?(2P0-2S) with both CCD-camera and S20 photo-multipliers simultaneously. From the received radial intensity distribution, we deduce the radial distribution of electron density.
