| Zusammenfassung | Ionization gauges are commonly considered to have identical sensitivity to hydrogen and deuterium due to the identical atomic configuration of the two gas molecules. We compared, experimentally, the sensitivity of twelve hot ionization gauges to hydrogen and deuterium and found significant differences between gauges. These differences depended on the specific gauge and systematically changed with operating treatments; this effect can be explained by a different, secondary electron production of hydrogen and deuterium ions when hitting the ion collector. |
