Diamond X-Ray Transmission Targets

Tungsten coated CVD diamond windows brazed to a metallic support frame have proven to be very useful as transmitting, high-power X-ray anodes. By irradiating the tungsten layer with an high-energy electron beam a single point X-ray source is formed which is perfectly suited for the high-resolution inspection of small objects.

In this application, diamond plays two roles: on the one hand side it acts as an efficient heatspreader that rapidly dissipates the heat from the focus zone, on the other hand side it acts as an X-ray transparent window.

Thus objects under investigation can be positioned very close to the X-ray point source - ideal conditions for the X-ray inspection with high resolution and high magnification.
