An inspection fixture includes a base member, a support member coupled to base member, and an intermediate member coupled to the support member or the base member. The support member includes a radiolucent material for limiting artifacts in imagery of an industrial article supported by the inspection fixture. Inspection arrangements and imaging methods are also described.

Provided are a cooling system with no refrigeration machine for an X-ray detector, and an X-ray imaging system using the system. The cooling system for an X-ray detector comprises: a cooling pipeline positioned on an X-ray detector; and a coolant transfer pipeline positioned at least partially in a support device of the X-ray detector and connected with the cooling pipeline to form a circulation loop, the circulation loop being provided with a circulating coolant therein. On the basis of the existing X-ray photography system, the configuration of a refrigeration machine can be removed from the cooling system, and the cooling of the detector can be realized with as few changes as possible, while meeting the temperature requirements of the normal operation of the detector and reducing costs.

A bus bar unit is provided with a plurality of bus bars and an insulating holder. The insulating holder holds the bus bars in a parallel arrangement and insulates between the bus bars. The insulating holder includes a molded portion, a wall portion and a groove portion. The molded portion covers an entire periphery of at least one bus bar from among the plurality of the bus bars. The wall portion is provided at a position spaced apart from a side surface of the molded portion to insulate the bus bars. The groove portion holds a remaining bus bar between the molded portion and the wall portion.

Disclosed is a radiation logging tool, comprising a tool housing; a compact generator that produces radiation; a power supply coupled to the compact generator; and control circuitry. Embodiments of the compact generator comprise a generator vacuum tube comprising a source generating charged particles, and a target onto which the charged particles are directed; and a high voltage supply comprising a high voltage multiplier ladder located laterally adjacent to the generator vacuum tube. The high voltage supply applies a high voltage between the source and the target to accelerate the charged particles to a predetermined energy level. The compact generator also includes an electrical coupling between an output of the high voltage supply and the target of the generator vacuum tube to accommodate the collocated positions of the generator vacuum tube and the high voltage power supply.
