Abstract
The present disclosure relates to the production and use of a multi-layer X-ray source target. In certain implementations, layers of X-ray generating material may be interleaved with thermally conductive layers. To prevent delamination of the layers, various mechanical, chemical, and structural approaches are related, including approaches for reducing the internal stress associated with the deposited layers and for increasing binding strength between layers.
Claims20
An X-ray source, comprising:
- an emitter configured to emit an electron beam;
- and
- a target configured to generate X-rays when impacted by the electron beam, the target comprising:
- a thermally-conductive substrate;
- two or more X-ray generating layers, wherein X-ray generating layers are separated by at least one intervening thermally-conductive layer;
- and
- one or more interface layers formed between a respective X-ray generating layer and one or both of the first thermally conductive layer or a respective intervening thermally-conductive layer.
