在这篇文章中，我们提出了一个等离子体诊断操作或计划的持续spheromak物理实验装置，现在在劳伦斯利弗莫尔国家实验室运行的概述。一组46壁装磁探头提供必要的数据，磁重建的泰勒松弛状态。罗戈夫斯基线圈测量在通量保持器中感应的电流。用CO_2激光干涉仪测量电子线密度。光谱测量包括一个绝对校准的光谱仪记录扩展域光谱仪，用于获得时间积分的可见紫外光谱和两个时间分辨真空单色仪，用于研究两个单独的发射线的时间演变。另一种时间积分光谱仪记录可见光范围内的光谱。滤波硅光电二极管测辐射热计提供总功率测量，16通道光电二极管空间阵列提供径向发射轮廓。等离子体和螺旋度注入的二维成像。
In this article we present an overview of the plasma diagnostics operating or planned for the sustained spheromak physics experiment device now operating at Lawrence Livermore National Laboratory. A set of 46 wall-mounted magnetic probes provide the essential data necessary for magnetic reconstruction of the Taylor relaxed state. Rogowski coils measure currents induced in the flux conserver. A CO2 laser interferometer is used to measure electron line density. Spectroscopic measurements include an absolutely-calibrated spectrometer recording extended domain spectrometer for obtaining time-integrated visible ultraviolet spectra and two time-resolved vacuum monochrometers for studying the time evolution of two separate emission lines. Another time-integrated spectrometer records spectra in the visible range. Filtered silicon photodiode bolometers provide total power measurements, and a 16 channel photodiode spatial array gives radial emission profiles. Two-dimensional imaging of the plasma and helicity injec...
