Improved Monte Carlo method for ion transport in ion-molecule asymmetric systems at high electric fields

摘要: An improved Monte Carlo method is developed for the simulation of ion transport in classical drift tube case ion-molecule asymmetric systems such as O−/O2 or N+/N2. The aim this new to overcome problem incident ions which vanish at relative high electric field due charge transfer electron detachment. These removal processes are compensated by a fictitious creation improves accuracy distribution function and swarm coefficient calculations. collision occurring weakly ionized gases room temperature (elastic collisions including energy exchange thermal motion background also inelastic collisions) taken into account. This then validated reaction coefficients have been given large range E/N (a part them first time literature) N+/N2 systems.
