Abstract:
A mechanism is proposed for the emission of a broad band VUV light to be emitted from the regenerative sooting discharges on the basis of unusually intense intercombination lines of C+(CII) and C++(CIII) that have been observed. Comparison of these high intensity intercombination lines with the allowed transitions of the highly excited and ionized C constituents of the sooting discharge indicates that one can exploit this mechanism to employ the regenerative soot as a VUV source. The emission of such a broad VUV band from the sooting discharges depends critically on the high energy electrons, metastable gas atoms and C ions trapped by the 3D cusp magnetic field contours.
