原子束支撑发射光谱很适合边缘诊断的需要；特别是，它提供了高的空间和时间分辨率，并且几乎不会引起等离子体的扰动。利用Li、He和h三种物质，在不同的速度范围内开发了原子束，通过它可以测量最重要的等离子体参数。解释了测量电子密度、离子温度分布和高电离杂质径向分布的原理，并描述了在TEXTOR上使用的原子源。本文介绍了在TEXTOR上获得的各种等离子体参数的最新结果，并进行了批判性的讨论。我们相信，等离子体湍流和等离子体边缘的二维特性将是未来的重要挑战。只有在技术开发上投入足够的努力，原子束才能提供解决方案。
Atomic beam supported emission spectroscopy is well suited to satisfy the needs of edge diagnostics; in particular, it offers high space- and time resolution and causes almost no perturbation of the plasma. Making use of the species Li, He and H. atomic beams have been developed, in different velocity ranges, by the help of which the most important plasma parameters can be measured. The principles for the measurement of the electron density and temperature profiles of the ion temperature profile and of the radial profiles of highly ionized impurities are explained and the atom sources used at TEXTOR are described. Recent results obtained on TEXTOR for various plasma parameters are presented and critically discussed. We are convinced that plasma turbulence and the two-dimensional character of the plasma edge will be important challenges for the future. Atomic beams may offer solutions only if sufficient efforts are invested into their technical development.
