Transparent X-ray Camera

X-ray experiments are an invaluable way to probe fundamental properties of materials. Constant improvements in synchrotron x-ray sources and experimental advancements are continuing to push and surpass the capabilities of commercially available x-ray detector performance. To help fill this technology gap, pioneering x-ray detectors must be brought out of the research lab and into commercialized products. To fully utilize the capabilities of modern light sources, it is critical to understand the x-ray beam properties throughout an experiment, with minimal disruption. Current technologies are reasonable for defining general beam position but lack the dynamic range and resolution to observe high-flux, short-pulsed, narrow x-ray beams generated by today’s synchrotrons. This work fills this need by commercializing a transparent x-ray camera that can be permanently placed in line with experiments, capable of reading photon fluxes of 107 – 1016 photons per second, with an average transmission above 5 keV of greater than 90%. Beamlines worldwide utilize beam focusing optics like toroidal mirrors and slits that demand assurance in beam position, size, shape, and flux from the x-ray source all the way to the sample. Currently, there is no commercial device that addresses all of these concerns in one, user friendly package. The size and pixel dimensions of the proof of concept device with commercialization will enable an early product launch to fill this need. Phase I included the initial technology transfer of a research level transparent x-ray camera. Mechanical, electrical, and software components were analyzed and preliminary designs completed to reduce electronic noise, increase dynamic range, and make the design compatible with multiple beamline configurations (i.e. in line, stand-alone, high vacuum compatibility). In addition, two proof of concept devices with advanced detector features for specialized applications were produced and tested: high density pixels (10 µm) and \ larger format (>3 mm2 active area). The primary objective of the proposed program is to leverage the research and development completed to date and commercialize the detector, making it available to the x-ray community. Commercial prototypes will be produced, optimized, and validated with application specific beamline testing. Prototype devices with alternative pixel features and advanced user options like those explored already will continue to be studied. With feedback from the user community a finalized commercial device, capable of satisfying current and future demands of synchrotron technology will be produced.
