Název v původním jazyce

Influence mercury traces on kinetics of pure nitrogen post-discharge at decreased wall temperature

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 very low mercury traces of about 3.7 ppb. The decaying plasma up to 50 ms was studied by the emission spectroscopy in the range of 300 - 850 nm. The discharge tube around the observation point (+- 3 cm) was immersed in liquid nitrogen. Three nitrogen spectral systems and NO-beta bands were identified, but no mercury lines were observed in the involvedspectral region. The total gas 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. As the uncontrolled oxygen traces were recorded in the mercury flow, the experiment with a nitrogen-oxygen mixture at the same discharge conditions was studied, too. The results showed strong quenching of the nitrogen pink afterglow by mer
