Аннотация

The effect of ion doping on the secondary emission characteristics of Mo, Pd and Pd-Ba alloy has been investigated. It was found that as a result of doping with low-energy barium ions, an intermetallic compound of the Pd-Ba type is formed in the Pd surface layer. The formation of a chemical compound between the substrate and the dopant contributes to a significant (threefold) increase in the secondary electron emission (SEE) coefficient. It was found that the Pd and Pd-Ba samples after doping with a large dose of Ba+ ions have almost the same secondary emission parameters. Doping of Pd-Ba first with barium ions, then with oxygen ions with energy of E0≤1 keV leads to a significant increase in the secondary electron emission (SEE) coefficient.
