A one-dimensional particle-in-cell (PIC) algorithm is applied to a planar plasma probe in contact with a weakly ionized plasma. The algorithm couples Poisson's equation and Newton's laws of motion to calculate the electric field and the forces on the charged particles. A new set of boundary conditions is developed to simulate the semi-infinite neutral plasma. Collisions between the charged particles and the background gas are incorporated using a Monte Carlo collision algorithm. Changes in the electrostatic sheath in response to changes in the voltage and the plasma density are consistent with previous experimental and theoretical results.
