Creation and Measurement of Air Plasmas

Abstract

The parent program focuses on minimization of power budget for the efficient creation of large volume, atmospheric pressure air plasmas, with minimum electron density of 10(exp 13)/cu cm and heavy species translational temperature not exceeding 2000 K. Since a thermal plasma with 10(exp 13)/cu cm electron density necessitates a heavy species temperature of approximately 4200 K. the stated program goals inherently define a nonequilibrium plasma. OSU's approach for attaining the program goals is two-pronged based on: (1) Creation of a low translational temperature, highly vibrationally excited environment in which the rates of principal electron loss channels are reduced by orders of magnitude. (2) Efficient electron production by means of an electron beam and/or application of a short pulse. high E/n electric field.
