PROMT 是 Rijnhuizen 托卡马克项目中使用的多位置汤姆逊散射系统。红宝石激光器发出的光被等离子体中的自由电子散射，并沿着 180 毫米的垂直弦被收集。可以解析多达 36 个空间元素来测量电子温度和密度分布。散射光由利特罗多色仪进行光谱分析，随后用增强电荷耦合器件相机进行检测。在密度为 2×1019 m−3 时，可以以 ~5% 的精度测量 50 eV–3 keV 范围内的电子温度。
PROMT is a system for multiposition Thomson scattering in use at the Rijnhuizen Tokamak Project tokamak. Light from a ruby laser is scattered by the free electrons in the plasma and is collected along a vertical chord of 180 mm. Electron temperature and density profiles can be measured resolving up to 36 spatial elements. Scattered light is spectrally analyzed by a Littrow polychromator and subsequently detected with an intensified charge coupled device camera. At densities of 2×1019 m−3 electron temperatures in the range of 50 eV–3 keV can be measured with an accuracy of ∼5%.
