Abstract
The velocities of rotational motion of atoms and ions in a plasma accelerator of the homopolar type operating under steady-state conditions were determined from Doppler spectral line shifts. The measuring instrument was a Fabry-Perot interferometer equipped for both photographic and photoelectric recording of the interference pattern. Comparison of the results obtained with the two recording techniques served to reveal the considerable advantages of photoelectric recording over photography in situations of the type in question, especially where the line contours are asymmetrical.
