我们描述了一种对螺旋等离子体源中的氩离子进行三维 (3D) 激光诱导荧光 (LIF) 诊断。通过在单个空间位置处使用三个不同的激光注入方向，执行 LIF 测量以确定 3D 离子温度和 3D 离子流矢量。然后在等离子体柱横截面的多个位置重复测量过程，以创建 3D 离子流、离子温度和亚稳态离子密度的二维 (2D) 图。 2D 平面中的扫描是通过将注入和收集光学器件安装在步进电机驱动的平台上来完成的。
We describe a three-dimensional (3D) laser-induced fluorescence (LIF) diagnostic for argon ions in a helicon plasma source. With three different laser injection orientations at a single spatial location, LIF measurements are performed to determine the 3D ion temperature and the 3D ion flow vector. The measurement process is then repeated at multiple locations in a cross section of the plasma column to create a two-dimensional (2D) map of the 3D ion flow, the ion temperature, and metastable ion density. Scanning in the 2D plane is accomplished by mounting the injection and collection optics on stepping motor driven stages.
