The latest High-Power Target is a transmission target consisting of an interaction layer made of tungsten and a special backing layer that provides improved heat transfer and lower focal spot temperature.
Its construction allows users to operate the x-ray tube with higher energies at the highest possible resolution, allowing for increased image contrast. Ideal for inspecting objects with low-contrast structures, or with high absorption structures.
As a rule, the thermal stress applied to the target increases with decreasing focal spot size and increasing tube power. Focal spot size, however, is a critical factor in determining geometric magnification and image resolution, while tube power influences the x-ray intensity output.
