UHV rotating fluid delivery system

A system for delivering fluid in an ultra high vacuum environment, comprising:

• a rotatable apparatus defining coolant channels;
• inlet and outlet line means operatively attached to the rotatable apparatus for rotation therewith and adapted to be operatively connected to the coolant channels;
• fluid inlet and outlet ports;
• and
• pliant inlet and outlet connector means connected, respectively, between the fluid inlet ports and the inlet line means and between the fluid outlet ports and outlet line means, the pliant inlet and outlet connector means moving in response to rotation of the rotatable apparatus.

An all metal sealed fluid delivery system for providing fluid to coolant channels in a rotatable crucible assembly in an ultra high vacuum environment comprising:

• rotating means for attachment to a spindle of the crucible assembly for rotation therewith;
• ductile sealing means for forming an ultra high vacuum seal and a fluid seal between the spindle and the rotation means;
• housing means having an aperture therein for attachment of the rotating means;
• fluid inlet and outlet line means extending from the coolant channels, through the spindle and the rotating means, and to an interior of the housing means;
• fluid inlet and outlet port means extending through port apertures in the housing means;
• at least one pair of bellows means mounted within the housing means and having first ends coupled to the fluid inlet and outlet line means and second ends coupled to the fluid inlet and outlet port means, during rotation of the rotating means a first of the at least one pair of bellows means coiling within an axis of rotation of the rotating means and a second of the at least one pair of bellows means uncoiling within the axis of rotation of the rotating means.
