Název v původním jazyce

Influence of Metal Traces on Kinetics of a Nitrogen Glow Discharge in Post-Discharge Period

Popis výsledku v původním jazyce

The work presents results obtained during spectroscopic observations of DC flowing post-discharges of pure nitrogen plasma and nitrogen plasma containing traces of mercury. The plasma was studied by the emission spectroscopy in the range of 300 - 850 nmwhere three nitrogen spectral systems were identified, NO-beta bands were observed just above the noise level at the latest decay times over 35 ms. The discharge and post-discharge were studied in nitrogen with mercury traces of about 3.7 ppb. The totalgas pressure was 700 Pa and the discharge current was kept at 150 mA. The relative populations of N_2 (B ^3 Pi_g), N_2 (C ^3 Pi_u) and N_2^+ (B ^2 Sigma_u^+) states were calculated in the dependence on the post-discharge time in the range of 3 - 40 ms. As the uncontrolled oxygen traces were recorded in the mercury flow, the experiment with a nitrogen-oxygen mixture at the same discharge conditions was added. The results showed strong quenching of the nitrogen pink afterglow by mercury tr
