Turnkey Digital Laue detector allows high throughput crystal characterisation within an hour from unpacking.

The camera allows unique back scattered geometry collection and ultimate alignment accuracy down to 0.3 degree.

Efficient beam delivery on sample enables near real time diffraction pattern recording.

Combined with motorised sample rotation, the system brings simpler and more flexible crystal orientation routines.

The acquisition software delivers ready to be indexed digital images from PC, to Linux remote controlled machines. 

Existing Laue set ups can be upgraded with turnkey solutions including : beam delivery X-ray source, collimators, goniometer / sample holder and system installation / integration.

Poly / Mono capillary and Doubly Curved Crystal X-ray optics

XOS and Photonic Science sign a European agency agreement covering the supply of X-ray optic / monochomator and integrated XBEAM microfocus sources to laboratories / synchrotrons / OEMs wishing to upgrade their current set up.

Polycapillary X-ray optics  allows faster and more flexible data collection routines over 100eV up to 40keV energy range. Thanks to high solid angle capture (few degrees) / optimised beam size (10m up to 10mm) / output focal range combination (2-500mm).  Over 1000 fold flux density gain (versus pinhole aperture) can be obtained depending on 2D point to point or point to parallel geometry used.

High spectral resolution / high sensitivity (down to ppb) requirements can be met using a doubly curved crystals instead of polycapillary X-ray optics.

The newly released Neutron Imaging Camera system consists of two high resolution intensified digital cameras coupled to a high performance neutron scintillator screen. This dual system allows a unique digital backscattered Laue diffraction pattern to be recorded as it features a centre hole to allow the neutron beam to pass through the camera system prior to reaching the sample This configuration allows the neutron scintillator to be positioned very close to the sample, so that a large solid angle of diffracted beams can be imaged.

Both cameras feature a high performance, 18mm ultra low noise image intensifier which is fibre-optically coupled to a high quantum efficiency, cooled CCD sensor with typical DT of > 40ºC to provide very high dynamic sensitivity.

Each camera has dual speed readout, on-chip binning and sub-area readout – the overall readout being a single image of 1680x1320 pixels. Full distortion correction provides perfect calibrated linear image geometry.

Ultra low noise, high sensitivity large area mosaic imaging detector, using cooled ICCD-based multiple camera systems, with custom-made geometry for optimum solid angle capture, with optimised scintillator of 6LiF:ZnS:Ag and coupling optics. The detector produces a single ‘letterbox’ format output image. The detector is based upon an octagon of scintillating plates that forms a hollow vertical cylinder 400mm in diameter and 400mm high with the neutron beam entering in the equatorial plane. Each of the eight segments is read out vertically by two cameras.

The eight independent corrected images from the different segments, automatically corrected, stitched together and calibrated against each other, give the camera a resolution of 2260(h)x7505(w) pixels. The detector construction will allow the change of the scintillator assembly. The flexible design will also ease the generation of new calibration map files resulting from scintillator change and camera service. The cameras employ a low noise intensified cooled CCD with FireWire readout, and have an optical pixel size at the scintillator input of 177µ square (no binning). The cameras have a 16-bit acquisition mode and a fast 12-bit readout mode. Exposures of 1ms to a few hours in dynamic integration mode are possible. On-chip binning from 1x1 to 8x8 are available. Software is based on supplied DLLs and sample C++ code for FireWire drivers to assist end-user driver development.

Other features are sequential acquisition mode with software selectable variable such as time between images etc. or external hardware trigger mode. Embedded distortion, stitching and gain response corrections are some of the many features designed to make the system easy to use in a research environment.
