XRF analyzer with separate source and detector heat sinks

A portable x-ray fluorescence (XRF) analyzer comprising:

• an x-ray source and an x-ray detector;
• an x-ray source heat-sink adjacent a side of the x-ray source;
• an x-ray detector heat-sink adjacent a side of the x-ray detector;
• the x-ray source heat-sink separated from the x-ray detector heat sink by at least 3 millimeters of a thermally insulating material.

A portable x-ray fluorescence (XRF) analyzer comprising:

• an x-ray source and an x-ray detector;
• an engine component casing;
• the x-ray source and the x-ray detector disposed in and substantially enclosed by the engine component casing;
• an x-ray source heat-sink disposed in an opening in the engine component casing and adjacent a side of the x-ray source;
• an x-ray detector heat-sink disposed in another opening in the engine component casing and adjacent a side of the x-ray detector;
• and
• the x-ray source heat-sink separated from the x-ray detector heat sink by a segment of the engine component casing.
