APPLICATION OF AN ALTERNATING ELECTRIC FIELD IN THOMSON MASS SPECTROGRAPH FOR TIME DISPERSION OF SPECTRA,
Abstract
A method for determining the time history of the spectral distribution of the ion component in plasmas is described. It employes a time-varying electric deflection field providing the dispersed record of the ion energy. A diagram of the analyzer is shown. Photometry of the film recordings also provides beam intensity information. This device was employed in analyzing plasma puffs of about 20 microseconds duration and the results are graphed. The relative concentration of the plasma ions (H(+), C12(+), Fe56(+)) is given; the main part of the puff contains essentially no impurities. The authors point out that peak concentrations of heavy ions coincided in time with light ion peaks; these occur in the portion of the plasma with a hydrogen concentration of not more than 30%.
