Abstract:

We discuss here some peculiarities in lead vapor pumping with resonance flash lamps and describe the experimental equipment used. The problem of spurious displacement current that may appear when switching the resonance lamp on is considered. Glow spectrum of lead vapor is found to markedly differ from the radiation spectrum of the pumping resonance lamp. Some spectral lines, intense in a pulsed discharge, are absent in the vapor glow. Other lines, on the contrary, are more intense in the glow spectrum. Appearance of the lead ion lines in the glow is indicative of photoresonance plasma formation in the chamber under the irradiation.
