Modeling of positive streamers in liquid argon

A numerical simulation is used to investigate the dynamics of positive streamers in liquid argon. It is shown that as in gases, the nature of the streamer propagation depends on the field strength in the discharge gap. It is established that electron-ion recombination in the streamer channel plays a significant role compared with streamers in gases. Pis’ma Zh. Tekh. Fiz. 25, 19–27 (February 12, 1999)
