The parameters of nonequilibrium microwave discharge in nitrogen in a tube in a rectangular waveguide
Annotation
Computer codes are developed for the processing of emission spectra of nonequilibrium plasma in nitrogen for the purpose of obtaining information about the translational Tg and rotational Trot temperatures, the populations of vibrational levels in the ground electron and electron-excited states, the electron energy distribution function, the electron concentration Ne, and the electric field intensity E. The computer codes are used to determine the parameters of microwave-discharge plasma in nitrogen in discharge systems of two types, namely, in a discharge tube (with a radius of 1 cm), which crosses a rectangular waveguide (plasmatron on the H10 wavelength, at a pressure of 1.7 torr and absorbed power density of 1.5 W/cm3), and in a discharge section of similar structure on the basis of prismatic resonator (at a pressure of 1.0 torr and absorbed power density of 0.4 W/cm3). The mechanisms of population of the N2(C3Πu) state are treated.
