其他摘要：The aim of this work was to explore the influence of the alternating voltage on the dynamical processes of the evaporator temperature. Temperature distribution of the evaporator, which is mostly of sophisticated configuration, determines the flow of charges in the vacuum system. Therefore FEM was choused for the calculation of the temperature distribution and dynamical processes of the evaporator temperature. The calculations allowed us to determine the time constant of these processes, which is alternating between 0.3 s and 0.9 s depending on the applied voltage and initial temperature of evaporator. Therefore the control system of evaporator temperature must to restart the control actions every 30 ms. Ill. 11, bibl. 4 (in English; summaries in English, Russian and Lithuanian).
