摘要
The possibility of achieving the high density of negative hydrogen ions NH- in a low-voltage cesium-hydrogen discharge is investigated. The NH- density is determined experimentally from the absorption of laser radiation due to the photodetachment of electrons from H- ions. The discharge plasma is investigated by the probe technique. The populations of the excited states of Cs atoms are determined from their emission intensities. With an input power of W approximate to (15-25) W/cm(2) in the discharge, densities of N-H_ similar to (10(12 _) 10(13)) cm(-3) are achieved. The self-consistent calculations of the plasma parameters in the discharge gap agree well with the experimental results. The absorption of laser radiation due to the photoionization of Cs atoms is investigated. It is shown that the role of this absorption mechanism is negligible. (C) 2003 MAIK "Nauka/Interperiodica".
