Abstract: A cryogenic tank includes a shell having an interior side, an exterior side, and an internal volume that is bounded by the interior side. The shell has a shape that includes at least two elongated lobes that are defined by partial cylinders that intersect each other. The partial cylinders extend lengths along central longitudinal axes that are offset from each other. The lobes include opposite domes that extend at opposite ends of the length of the corresponding partial cylinder. The cryogenic tank includes an internal reinforcement frame having a web of elongate frame members extending within the internal volume. The frame members extend along the interior side of the shell such that lengths of the frame members extend along paths that follow the profile of the interior side of the shell. The internal reinforcement frame is configured to distribute loads exerted on the shell along at least three different directions.

Abstract: An x-ray tube 10 is provided including an anode mounted to a rotatable shaft positioned within a center bore of a stem element, a bearing assembly positioned between the rotatable shaft and the stem element, and at least one liquid metal shunt in thermal communication with both the rotatable shaft and the stem element, located adjacent to the anode between the anode and the bearing assembly, and directing heat generated at the anode away from the bearing assembly by allowing heat to flow from the rotatable shaft into the stem element prior to heat reaching the bearing assembly.
