摘要： An apparatus includes a switch cabinet and a device housing. The device housing is adapted to accommodate a component of a device and the switch cabinet is adapted to accommodate electrical equipment for the device. The switch cabinet is operable to be moved between an open position and a closed position relative to the device housing. When in the closed position a wall of the switch cabinet closes off an opening in the device housing, and when in the open position the wall of the switch cabinet is removed from the opening in the device housing so as to expose that opening.

摘要： An X-ray module includes a housing; an electron gun that emits an electron beam inside the housing; a target disposed inside the housing and fixed to the housing, to generate an X-ray when the electron beam is incident on the target; and a deflection unit including a permanent magnet and disposed outside the housing, to deflect the electron beam by means of a magnetic force of the permanent magnet. The deflection unit includes a heat insulating member disposed at least between the permanent magnet and the housing. A thermal conductivity of the heat insulating member is lower than a thermal conductivity of the permanent magnet.

摘要： A method for controlling the movement of an X-ray source via a suspension device includes obtaining, during a movement of the suspension device along the rail, a first speed of the suspension device at the first reference point. The first reference point may correspond to a first target position. The method may also include determining whether the first speed of the suspension device at the first reference point is less than a threshold speed. In response to a result of the determination that the first speed of the suspension device at the first reference point is less than the threshold speed, the method may further include actuating a control device to move the suspension device to the first target position.

摘要： 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.
