Abstract:

The formative time dependence on working voltages t_f(U) in nitrogen is determined: (1) from the Laue diagrams, by taking the values where the linear approximation of the electrical breakdown time delay (t_d) intersects the time axis, (2) from histograms, by taking the minimum values of the delay times for the formative time, and (3) from a difference t_f = - ≍ - σ (t_d), where standard deviation σ,(t_d) is approximately equal to the mean of the statistical time delay . The breakdown time delay measurements are supported by oscilloscopic measurements of the voltage drop and the current rise time during inception of the discharge. Several simple models were applied to describe the experimental formative time dependence on working voltages t_f,(U) and a good agreement with experimental data was found.PACS Nos.: 51.50.+v, 52.80.-s

Nous déterminons comment les voltages d'opération t_f(U) affectent le temps de formation dans l'azote : (1) à partir des diagrammes de Laue, en prenant les valeurs où l'approximation linéaire du délai temporel du claquage électrique (t_d) intersecte l'axe du temps, (2) à partir des histogrammes, en prenant les valeurs minimales des temps de délai pour le temps de formation et (3) à partir de la différence t_f= - ≍ - σ (t_d) où (t_d) est approximativement égal à la moyenne du délai de temps . Les mesures de délai du temps de claquage sont confirmées par des mesures sur oscilloscope du temps de chute de voltage et d'augmentation du courant au début de la décharge. Nous utilisons plusieurs modèles simples pour décrire la dépendance du temps expérimental de formation sur les voltages d'opération t _f(U) et nous obtenons un bon accord avec les données expérimentales.[Traduit par la Rédaction]
