Abstract. A review of our investigations on the time delay of electrical
breakdown in gases at low pressures has been presented in this paper. Statistical
analysis of time delay using Laue distributions and histograms of experimental
data has been performed. The influence of different parameters (overvoltage,
electrodes' temperature and material, glow current) on time delay has been
considered. Memory curves have been analyzed and applied to estimate positive
ion recombination time, nitrogen atom catalytic recombination time as well
as deexcitation time of metastable states in kripton.
VREME KAŠNJENJA ELEKTRIČNOG PROBOJA
U GASOVIMA NA NISKIM PRITISCIMA
U ovom radu je prikazan pregled naših istraživanja vremena kašnjenja električnog
proboja u gasovima na niskim pritiscima. Izvršena je statistička analiza
korišćenjem Laue-ovih raspodela i histograma eksperimentalno dobijenih
podataka. Razmatran je uticaj raznih parametara (prenapona, temperature
i materijala katode, struje pražnjenja) na vreme kašnjenja. Razmatrane
su memorijske krive i njihova primena za procenu vremena rekombinacije
pozitivnih jona, vremena katalitičke rekombinacije atoma azota kao i vremena
deekscitacije metastabilnih stanja u kriptonu.
