摘要
使用基于锂原子与电子碰撞激励产生荧光以测量电子密度的新方法,并用CCD摄象机和S20光电倍增管同时观察了锂原子6708A(~2P^0—~2S)的荧光信号,并从光强分布曲线推算出电子密度的径向分布。
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 6708A (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.
