Ion Drift Velocity Benchmark

Application ID: 14415

The drift velocity of Ar+ is calculated using a Monte Carlo simulation in which the elastic collisions of Argon ions with ambient neutrals are explicitly modeled. The model uses energy-dependent collision cross-section data from experiment.

The average ion velocity values are consistent with experimental data over a wide range of reduced electric field magnitudes. This agreement suggests that Monte Carlo simulation of elastic collisions between particles may be applied to a wide variety of devices.

This model example illustrates applications of this type that would nominally be built using the following products:
