Abstract
Time lag of the line‐intensity jump in a decaying argon arc was experimentally investigated. Especially, the time of intensity peaks during the intensity jump was measured in a wall‐stablized argon arc after the current interruption. The measurements were made for seven spectral lines of ArI. The result showed that the peak time changed depending on the ionization energy of the excited level. Namely, the peak time increased with increasing the ionization energy of the level. The peak time at lower levels involved additional delay to that predicted by the equilibrium theory. It was also shown that the amplitude of the jump at these lower levels did not reflect the accurate gas temperature.This publication has 4 references indexed in Scilit:
