Various systems are provided for a power supply system. In one example, the system includes a power distribution unit configured to receive power from a main power source and an uninterruptible power supply (UPS), wherein the UPS is configured to directly power an output AC load, the UPS is further configured to power an output DC load after coupled through one or more transformers.

An x-ray generating unit includes an x-ray tube that is substantially transparent to x-rays. A cathode is within the x-ray tube and defines a plurality of spaced apart cavities. An anode includes a material that emits x-rays when impacted by electrons. A plurality of filaments is each disposed in a different one of the cavities. Each of the filaments is electrically coupled to each other and to an activating voltage source in parallel. Each of the filaments emits a focused electron beam directed to a different predetermined spot on the anode upon application of a predetermined voltage between the cathode and the anode, thereby causing the anode to generate x-rays. Each of the plurality of spaced apart cavities is aimed at the anode so that each predetermined spot on the anode is separated from each other spot by a gap that is not impacted by an electron beam.

There is provided an X-ray inspection apparatus that inspects an inspection object by irradiating the inspection object with X-rays and detecting transmitted X-rays, the apparatus includes a module group (X-ray detection portion) which is disposed inside a housing and in which an electric component that is vulnerable to dew condensation caused by cooling of cooling means is mounted, a humidity sensor that monitors a humidity inside the housing, dehumidifying means (air conditioner) for dehumidifying an inside of the housing, and a control portion that performs supplying of power to the module group when the humidity monitored by the humidity sensor is equal to or lower than a predetermined value.

The invention discloses X-ray machine ray tube heat dissipation device which comprises a heat dissipation pool and an X-ray machine ray tube arranged in the heat dissipation pool, wherein the heat dissipation pool is provided with a water inlet and a water outlet, and the water outlet of the heat dissipation pool is communicated with the water inlet of water tank.

The electron beam is typically dynamically steered after its generation on the path to the target. The steering is performed by one or more source coils. These coils produce the magnetic field outside the vacuum vessel allowing air/water/oil cooling to remove undesired heat. The magnetic field is then picked up inside the vacuum vessel with pole pieces and guided towards the region where the magnetic field is needed to steer the electron beam.

An x-ray source has a target assembly including a target, an electron source for generating electrons to impact the target, and a flight tube assembly separating the target assembly from the electron source and transporting a coolant to the target assembly.
