Abstract : The stagnation-point Langmuir probe theory is presented, valid for supersonic flow with completely frozen but low degree of ionization. It is shown that under certain cold-wall conditions, diffusion and compression within a region of the stagnation point the boundary layer act to exactly balance one another, with the result that the ion density remains constant throughout this region, and thus the probe characteristic curve exhibits a nearly constant ion saturation limit.
