CVD Diamond X-Ray Beam Monitors

Conventional X-ray beam position monitors interrupt the X-ray beam and motorized stages are required to move them.

Thin diamond foils, on the other hand side, offer the possibility to realize transparent X-ray beam position monitors that can remain in the beam. This application takes advantage of the fact that diamond is a low-Z material, optically transparent and radiation resistant. By measuring the fluorescence light generated in the foil using a simple CCD camera both, the beam intensity, position and profile can be easily monitored.
