摘要： In one embodiment, an X-ray source is provided that includes one or more electron emitters configured to emit one or more electron beams and one or more source targets configured to receive the one or more electron beams emitted by the one or more electron emitters and, as a result of receiving the one or more electron beams, to emit X-rays. Each source target of the X-ray source includes a first layer having one or more first materials; and a second layer in thermal communication with the first layer and having one or more second materials. The first layer is positioned closer to the one or more emitters than the second layer, the first material has a higher overall thermal conductivity than the second layer, and the second layer produces the majority of the X-rays emitted by the source target.

摘要： A measurement system includes a cable having a length, a light source, at least one detector, and at least one processor. The light source is operably coupled to the cable and is configured to transmit an optical signal to the cable. The at least one processor is operably coupled to the cable and configured to: receive a scattered signal from the cable responsive to the optical signal transmitted to the cable; map the scattered signal to the length of the cable; and de-convolve a spatial averaging effect of the scattered signal using a weighting profile corresponding to the light source and the cable to generate a distributed property profile defined along the length of the cable.
