利用注入Li束的光谱测量了TEXT托卡马克等离子体的密度分布和极向场分布。中性Li束以高达95 keV的能量注入，在托卡马克射击期间观察到碰撞和激光诱导荧光。在一个完整的拍摄过程中获得径向和时间剖面。该技术对大型托卡马克的适用性取决于几个参数，包括（但不限于）束流穿透，可靠性，空间/时间分辨率和信噪比。因为这种基本技术获得局部测量，所以它也适用于非对称设备。将讨论这些应用程序。
Spectroscopy of an injected Li beam has been used to determine both the plasma density profile and the poloidal field profile on the TEXT tokamak. The neutral Li beam is injected at energies up to 95 keV and both collisional and laser‐induced fluorescence are observed during a tokamak shot. Radial and temporal profiles are obtained during a complete shot. The applicability of this technique to larger tokamaks depends on several parameters including (but not limited to) beam penetration, reliability, spatial/temporal resolution, and signal‐to‐noise ratio. Because this basic technique obtains local measurements, it is also applicable to nonsymmetric devices. Such applications will be discussed.
