Paschen's law studies in cold gases

TL;DR

This study investigates Paschen's law in cold gases, revealing deviations at micro gaps and temperature-dependent shifts, with implications for understanding electrical breakdown in various gases at different temperatures.

Contribution

It provides new experimental data on Paschen's law deviations at micro gaps and in cold environments, combining empirical results with theoretical explanations.

Findings

Deviations from Paschen's law at micro gap distances

Significant shift in breakdown voltage at lower temperatures

Results explained by combining Paschen's law and ideal gas law

Abstract

The break-through voltage over small gaps has been investigated for differing gap distances, gas pressures, and gas temperatures in nitrogen, neon, argon and xenon gases. A deviation from Paschen's law at micro gap distances has been found. The breakthrough behavior of the fill gas in colder environments was tested as well. A significant shift of the curve relative to the results at room temperature was observed. The results can be explained by combining Paschen's law and the ideal gas law.
