“…Unfortunately there is no adequate model for non-equilibrium discharge development in dense media. Here we use the "dense gas" approach 8,9 to estimate the electric field needed for water ionization. The "dense gas" approach assumes that the liquid is a gas but with high particle number density.…”

This paper presents the temporally resolved images of plasma discharge in de-ionized water. The discharge was produced by high voltage pulses with 0.3 ns rise time and 10 ns duration. The temporal resolution of the imaging system was one nanosecond. A unique three-stage process, including a fast ignition at the leading edge of the pulse, quenching at the plateau of the pulse, and self re-ignition at the trailing edge of the pulse, was observed in a single pulse cycle. The maximum measured propagation velocity of the plasma discharge was about 1000 km/s. The possibility of direct ionization in water under high reduced electric field conditions was discussed.

“…Electrons surviving recombination are drifted in the MC to the level of the liquid/gaseous argon interface with a velocity of 0.93 mm/µs. Drifted electrons undergo diffusion, with transverse and longitudinal components of 4.8 cm 2 /s [41] and 18 cm 2 /s [42], respectively. An electron drift lifetime of 15.8 ms, as measured by DarkSide-50 with 83m Kr calibration data, is introduced to take into account the effects of impurities in LAr.…”

A: A Geant4-based Monte Carlo package named G4DS has been developed to simulate the response of DarkSide-50, an experiment operating since 2013 at LNGS, designed to detect WIMP interactions in liquid argon. In the process of WIMP searches, DarkSide-50 has achieved two fundamental milestones: the rejection of electron recoil background with a power of ∼10 7 , using the pulse shape discrimination technique, and the measurement of the residual 39 Ar contamination in underground argon, ∼3 orders of magnitude lower with respect to atmospheric argon. These results rely on the accurate simulation of the detector response to the liquid argon scintillation, its ionization, and electron-ion recombination processes. This work provides a complete overview of the DarkSide Monte Carlo and of its performance, with a particular focus on PARIS, the custommade liquid argon response model.

“…Relevant theoretical contributions in modeling the diffusion processes of electrons in liquid argon originate from Cohen and Lekner [105], and Atrazhev and Timoshkin [106]. The theory indicates values for the transverse and longitudinal diffusion coefficients of D T = 16.3 cm 2 /s and D L = 6.2 cm 2 /s respectively at an electric field strength of 500 V/cm.…”
