Abstract
The effect of ionization on the presheath is analyzed kinetically in flowing magnetized plasma with finite ion temperature. Ion distributions along the presheath are obtained self-consistently with Boltzmann electrons. Sheath potential, ion sheath current density, and ratio (R) of upstream to downstream current density are obtained as a function of plasma drift velocity (Vd) and ionization rate (σi). Calibration factor (K) in the form of R=exp[KM] decreases with σi, where M is the drift velocity in units of [(ZTe + Ti∞)/mi]0.5.
