X-ray detector delivers more pixels, faster data

2011 R&D 100 Winner
Brookhaven MaiaX-ray microprobe instruments for synchrotron X-ray fluorescence experiments that analyze elemental and chemical constituents in biomolecular, geochemical, and materials research are in high demand. Brookhaven National Laboratory, Upton, N.Y., and Commonwealth Scientific and Industrial Research Organisation, Clayton, Australia, have developed an X-ray fluorescence detector system that produces high-definition images with 1,000 times the number of pixels as compared to conventional step-and-repeat spectroscopy systems. The detector also speeds data collection by a factor of 100.

The Maia X-ray Microprobe Detector system is a breakthrough advance for data acquisition rates for synchrotron X-ray fluorescence (SXRF) and X-ray absorption spectroscopy (XAS) at micrometer- to nanometer-scales. The high frame rates of the Maia detector system make 3D imaging modalities much more practicable. The developers anticipate that the detector will allow fluorescence tomography and XANES full-spectral chemical state imaging to become routine.

The Maia system allows rapid, continuous scanning of samples, providing typical pixel dwell times in the sub-millisecond range, while analyzing the data stream in real time to generate elemental maps immediately during the data acquisition. Multi-megapixel images can be acquired in a few hours versus competitive systems that take weeks to acquire such images.
