Ion Current to a Probe in Collisional Mode Taking Into Account Ionization in Plasma Bulk
- 6 Downloads
Analytical expressions were produced for the space charge sheath thickness and ion current to the sheath in collisional mode in cylindrical geometry. Comparison was performed with numerical solution to Poisson’s equation without dividing into the sheath and the plasma. Approximating formulas were provided for a wide range of pressures.
