ABSTRACT:
There is disclosed a crucible assembly comprising: (a) an electrically conductive tube having a first end portion and a second end portion and defining an opening in the surface of the tube, wherein the tube defines an imaginary horizontal line which bisects the cross-sectional dimension of the tube and an imaginary vertical line which bisects the cross-sectional dimension of the tube; and (b) at least one power connection area, operatively associated with the first end portion of the tube, wherein for the crucible assembly having only one power connection area associated with the first end portion, the one power connection area is positioned above the imaginary horizontal line on the same side of the horizontal line as the opening in the tube surface, wherein for the crucible assembly having at least two power connection areas associated with the first end portion, the at least two power connection areas permit coupling of at least two power cables.
