Abstract
A vaporizing crucible for vapor depositing systems, especially for electron beam heating, includes a plurality of side-by-side segments held in contact with one another by an adjustable compression device. The individual segments have between them layers of a resilient, electrically conductive material which forms a joint between adjacent segments. The segments are surrounded by a frame in which the adjustable compression device is positioned for the transfer of current and compressing the segments. A layer of resilient conductive material can also be positioned between the compression device and the lateral surfaces of the segments, extending perpendicular to the joints. The frame can also include a hollow base on which the segments rest. A layer of resilient, electrically conductive material can be positioned between the segments and the hollow base.
