Emission characteristics of electron-beam evaporators

The evaporation rate from a real evaporator is modeled with allowance for t he effects of the interaction of the electron beam with the evaporant and t he heat-transfer process in the evaporator. The emission characteristics fo r a real evaporator of finite dimensions during the sublimation or evaporat ion of a solid in cases where the evaporation rate is a function of time an d space are presented. The variations of the shape of the evaporation front and the crater shape during evaporation are calculated. (C) 2000 The Optic al Society of America. [S1070-9762(00)02204-1].
