在斯图加特大学空间系统研究所对氙进行激光诱导荧光测量，这将在不久的将来应用于离子推进器的等离子体诊断研究。介绍了中性氙的双光子激发、校准程序和粒子密度测定的基本方法。确定了可用装置的检测能力的理论极限。首先介绍了用冷气池在不同压力水平下获得的激光光谱结果。最后，讨论了进一步扩大压力范围的方法。
Laser induced fluorescence measurements on xenon are performed at the Institute for Space Systems of the Universitat Stuttgart which will be applied to plasma diagnostic investigations of ion thrusters in the near future. The two-photon excitation of neutral xenon is described as well as calibration procedures and the basic methods for particle density determination. A theoretical limit for the detection capabilities of the available set-up is determined. First laser spectroscopic results at different pressure levels, obtained with a cold gas cell for calibration purposes, are presented. Finally, methods for a further extension of the pressure range are discussed.
