本文介绍了在最近建成的持续球马克物理实验（SSPX）上新安装的一个利用CO2激光干涉测量的密度诊断装置和一个利用干涉滤光片和光电倍增管的Hα诊断装置。Hα诊断的首次诊断结果有助于理解新SSPX实验中的击穿物理。低噪声密度数据验证了减少振动和电子拾取的技术。新干涉仪的数据处理电子设备可以产生相当于16个条纹位移的明确的密度数据。密度数据对于理解粒子源和SSPX的J/ne参数也至关重要。
A newly installed density diagnostic using CO2 laser interferometry and an Hα diagnostic using interference filters and photomultiplier tubes for the recently constructed sustained spheromak physics experiment (SSPX) are described. First diagnostic results of the Hα diagnostic were useful to understand the breakdown physics in the new SSPX experiments. Low-noise density data validates techniques to reduce vibration and electronic pickup. The data-processing electronics of the new interferometer can yield unambiguous density data that is equivalent to 16 fringe shifts. Density data is also critical to understand the particle source, and the J/ne parameter for SSPX.
