A comparative analysis of the effect of temperature and laser activation on the values of the secondary electron emission coefficient (SEEC) and the work function eφ of the alloy Pd-Ba (Ba - 1.5 at.%) was carried out. It is shown that the optimum energy density of laser irradiation is ~ 2 J∙cm-2. The main reasons for the decrease in the emission efficiency of Pd-Ba for prolonged warming have been determined.
