Abstract
In ion sources, up to a third of the power released in a plasma discharge is carried away from the plasma in the form of ultraviolet radiation. Two main mechanisms for the formation of radiation are considered: radiation from excited atoms of the propellant and from ion-electron recombination coming out of plasma onto the surface bordering the discharge. The radiation-absorption coefficients of perforated electrodes of ion-extraction systems are determined.
