“…3) On the other hand, a probe measurement method using two electrodes with different secondary electron emission coefficients was proposed 4) and demonstrated. 5) At around the same time, under the condition of large secondary electron emission coefficients ($1), a new method of measuring plasma potentials using a probe was proposed and demonstrated. 6,7) Under that condition, multiple values of floating potentials of probe electrodes were also investigated in plasmas with energetic electrons from a hot filament, which was deeply negatively biased.…”

The valence band structure of the (100) face of substoichiometric VN and VC has been studied using angle-resolved photoelectron spectroscopy. The experimental results are compared with theoretical spectra, calculated for the stoichiometric composition. The overall agreement between experiment and theory is found to be fairly good concerning both the trends in the peak dispersions and the relative peak intensities, although discrepancies in absolute peak positions occur. The similarities and differences in the spectra from the (100) face of VN and VC are also briefly discussed.

Electric probe methods for diagnostics of plasmas are reviewed with emphasis on the link between the appropriate probe theories and the instrumental design. The starting point is an elementary discussion of the working principles and a discussion of the physical quantities that can be measured by the probe method. This is followed by a systematic classification of the various regimes of probe operation and a summary of theories and methods for measurements of charged particle distributions. Application of a single probe and probe clusters for measurements of fluid observables is discussed. Probe clusters permit both instantaneous and time-averaged measurements without sweeping the probe voltage. Two classes of applications are presented as illustrations of the methods reviewed. These are measurements of cross sections and collision frequencies (plasma electron spectroscopy), and measurements of fluctuations and anomalous transport in magnetized plasma.
