Description

The use of very high quantum efficiency photomultipliers (16% up to 8600 A) makes it possible integrally to observe the spectrum of light scattered by a plasma for a ruby laser. This report describes the set of optical apparatus and the electronic devices for taking the scattered light spectrum. The obtained spectra are highly asymmetrical after the manner of the asymmetry predicted by the Theory of Relativity. These results have not yet been interpreted (v/sub D//v/sub the/ = 4%). Diagnostic (interpretative) sensitivity permits the measurement of very low electron densities
