Constricted Discharges in the Rare Gases. I. Spectroscopic and Electrical Measurements

摘要: A description of the visual characteristics some constricted discharges in rare gases using dc, rf, and microwave excitation is given. These require power inputs from 20 to greater than 100 W/cc. The results a series spectroscopic electrical measurements made on these indicate range plasma parameters encountered. Gas temperatures were measured intensity distribution spectra several diatomic molecules. gas temperature falls 2000° 3000°K, but atomic levels are not equilibrium at this temperature. charge density around 1014/cc continuum intensity, line broadening, measurements. electron energy Maxwellian with an average which between 1 2 eV. Thus, plasmas lie ``thermal'' ``cold'' their properties. recombination process probably has contributions both dissociative dielectronic...
