초록

드리프트-확산 근사식을 이용한 1차원 유체 방정식으로부터 선형적 안정성 이론을 전개하여 Tosend 방전에서 전자 확산이 불안정성에 미치는 영향을 관찰하였다. 본 연구에서 관찰된 바에 따르면 Townsend 불안정성은 전자 확산과 공간 전하에 의해 형성된 전기장의 효과가 결합되어 발생하며, 공간전하에 의한 효과가 작은 영역, 즉 방전 전류가 낮은 영역에서는 전자 확산 효과가 커질수록 불안정이 더 빨리 진행된다는 것이 발견되었다.

The role of the electron diffusion on the stability of a Townsend discharge was investigated with the linear stability theory for the one-dimensional fluid equation with drift-diffusion approximation. It was proved that the discovered instability occurs as a result of the coupled action of electron diffusion and the perturbed electric field by space charge. The larger electron diffusion results in the faster growth rate at the regime of small perturbation of the electric field by space charges.
