Abstract
The ion current to a cylindrical probe is considered with allowance for volume ionization, ion–neutral collisions, and the ion orbital moment. A model based on the molecular dynamics method and applicable in a wide range of plasma parameters (rp/λD= 0.01–100, ri/λD= 0.002–200, νi/ω0i= 0.01–0.05, and Ti/Te = 0−0.01) is proposed A convenient representation of the dependence of the relative ion current density on the Langmuir coefficient β2 and a technique for determining the plasma density from simulation results are offered.
