Simulations of strongly coupled ions at a liquid-gas interface in time projection chambers

Abstract

Molecular dynamics computer simulations of a Lennard-Jones uid are used to describe the liquid-gas interface created in massive two-phases argon time projection chambers. The study intends to show the formation of the interface from a single phase state. The results allow us to set the initial conditions needed for future simulations of this type of systems. Additionally, once the interface is easily recreated, it shows a first approximation to the experimental scenario with the introduction of ions, as well as an explanation of the limitations encountered during the simulations.
