Abstract

The fast gas heating in pure nitrogen excited by a nanosecond discharge in a capillary tube at conditions of high specific deposited energy at electric fields 200-300 Td is investigated experimentally and numerically in 1D axially symmetric geometry. The measured initial radial distribution of excited species was considered as initial electron density profile in calculations. The translational temperature of the ground state of molecular nitrogen was measured by emission spectroscopy of (0-0) optical transition of the second positive system of molecular nitrogen. The fast increasing of translational temperature was observed. A good agreement between experimental and numerical results was achieved.
