Jif. Palop et al., THEORETICAL ION CURRENT TO CYLINDRICAL LANGMUIR PROBES FOR FINITE IONTEMPERATURE VALUES, Journal of physics. D, Applied physics, 29(11), 1996, pp. 2832-2840
A new theoretical model for the potential distribution in the surround
ings of a cylindrical conductor placed inside a neutral plasma permitt
ed us to analyse the effect of the positive ion thermal motion on the
ion current collected by a cylindrical Langmuir probe. The new theoret
ical model includes the ABR (Allen-Boyd-Reynolds) theory as a limiting
case, which is that of a negligible ion temperature compared to the e
lectron temperature.
