Abstract

Accurate modelling of electron transport in plasmas, plasma-liquid and plasma-tissue interactions is depen- dent on (i) the existence of accurate and complete sets of cross-sections, and (ii) an accurate treatment of electron transport in these phases. In this presentation, we will highlight our progress towards the provision of electron- biomolecule cross-section sets for water and THF by comparison of calculated transport coefficients with those measured using a pulsed-Townsend swarm experiment. Modelling of electron transport in gases, liquids and soft-condensed matter is considered through appropriate generalisations of Boltzmann's equation to account for spatial-temporal correlations present in liquids including self-trapping of electrons into bubble states, and com- bined localised-delocalised nature of transport. Solutions of Boltzmann’s equation are made within a multi-term framework, avoiding the well-known restrictions associ- ated with the 'two-term' approximation.
