“…• Pressure and temperature: Breakdown fields increased with increasing pressure in LN [11,20] and LHe [14,21]. However, some earlier studies in LN saw a decrease in breakdown fields with increasing temperature, [11] which correlates directly with pressure.…”

A: As noble liquid time projection chambers grow in size their high voltage requirements increase, and detailed, reproducible studies of dielectric breakdown and the onset of electroluminescence are needed to inform their design. The Xenon Breakdown Apparatus (XeBrA) is a 5-liter cryogenic chamber built to characterize the DC high voltage breakdown behavior of liquid xenon and liquid argon. Electrodes with areas up to 33 cm 2 were tested while varying the cathode-anode separation from 1 to 6 mm with a voltage difference up to 75 kV. A power-law relationship between breakdown field and electrode area was observed. The breakdown behavior of liquid argon and liquid xenon within the same experimental apparatus was comparable.

“…The experimental results are noticeably less than those given by the streamer theory because the break down occurs in the medium disturbed by a long time voltage application. The breakdown voltages mea sured in commercial grade liquid helium are still lower [14,34]. It clearly illustrates the influence of contam inants on the dielectric strength of liquefied helium even at cryogenic temperatures.…”

The kinetic Boltzmann equation is applied to determine the electron energy distribution function in condensed helium over a wide range of pressures and temperatures. Account is taken of all the effects influ encing the electron kinetics in dense media. The electron multiplication rates and basic electron transport coefficients in condensed helium at atmospheric and elevated pressures have been determined. Starting from the streamer theory, the limiting breakdown characteristics of condensed helium are calculated. The theoret ical findings are compared with available experimental data. For liquid helium the long standing fundamen tal problem is first solved of the intrinsic dielectric strength determined exclusively by the electron processes in a liquid itself rather than in gaseous bubbles formed at the prebreakdown stage. Comparison with experi mental data allows also answering the question of how the voltage application duration and contaminants affect the breakdown characteristics of liquid helium.
