Loss Processes of Metastable Particles in Cylinder Type Discharge Chamberwith Different Reflection Coefficients

Abstract

Loss processes of the metastable nitrogen molecules in the low pressure region have been investigated using the one dimensional diffusion equation analysis which was taken account of the reflection phenomenon at the boundary.
The theoretical treatment of the diffusion equation is expanded to the three dimensional space. The variation of the density distribution of the metastable molecules N2(A3∑u+) are calculated from the solution of the diffusion equation which is solved under the different reflection coefficients at each of electrodes and at the cylindrical wall. This paper describes the influence of the density distribution by the reflection phenomena of N2(A3∑u+). Furthermore, the influence of the effective lifetime metastable molecules is reported under different reflection coefficients of the diffusing metastable molecules.
