We describe electron temperature measurements in the SSX MHD wind tunnel using two different methods. First, we estimate Te along a chord by measuring the ratio of the C_III 97.7 nm to CIV 155 nm line intensities using a vacuum ultraviolet monochrometer. Second, we record a biasing scan to a double Langmuir probe to obtain a local measurement of Te. The aim of these studies is to increase the Taylor state lifetime, primarily by increasing the electron temperature. Also, a model is proposed to predict magnetic lifetime of relaxed states and is found of predict the lifetime satisfactorily. Furthermore, we find that proton cooling can be explained by equilibration with the electrons.

The appearance of third charged particles groups has been fixed when the laser radiation interacted with metal target in rarefied environ gas. The intensity of opti-cal range laser radiation was ~109 W/cm2. The opportunity of using Langmuir probe for diagnosing plasma processes with nanosecond resolution has been demonstrated. The results of electron temperature measurements have agreed with results of estimate model calculations for the two fasted groups of particles in the absorbtion area (for experimental conditionals).
