Electron swarm transport coefficients in CO - measurements and kinetic studies

The electron swarm transport coefficients (bulk drift velocity, bulk longitudinal component of the diffusion tensor, and effective ionization frequency) in CO are investigated for a wide range of the reduced electric field by means of measurements and kinetic calculations. The set of data contains results of measurements in a scanning drift tube apparatus under time-of-flight conditions as well as of kinetic swarm calculations using solutions of the electron Boltzmann equation and Monte Carlo simulations. In addition to the bulk drift velocity, bulk longitudinal component of the diffusion tensor, and effective ionization frequency, results of the average electron energy, flux drift velocity, flux longitudinal component of the diffusion tensor, flux and bulk transversal component of the diffusion tensor, bulk longitudinal and transversal characteristic energy as well as the effective steady-state Townsend ionization coefficient are given.
