Abstract

An absorption spectroscopy technique with temporal resolution using a conventional spectral source operating in pulsed mode has been used to determine the temporal distribution of neon metastable atoms density in the afterglow of a high voltage pulsed hollow cathode discharge plasma. The measured values for Neon 23P2 state density in the 40 - 120 μs temporal afterglow range are found to lay from 1.2 × 1012 ± 20% cm-3 to 3 × 1010 ± 20% cm-3 ..
