Abstract
An electron-beam apparatus for evaporating material is disclosed. The apparatus comprises a rotatable hearth on which the evaporant material can be placed and an electron-beam source which can be energized to evaporate the material. The apparatus is compact and durable because the electron beam source occupies a protected location which is closer to the rotational axis than is the hearth.
