Xspress 3 at HXN Beamline

A team of beamline scientists at Brookhaven National Laboratory have undertaken a development to make the Hard X-Ray Nanoprobe (HXN) beamline preeminent in the growing selection of nanoprobes being built around the globe. HXN strives for unprecedented goals in hard x-ray resolution and has made excellent progress towards achieving those. Xspress 3 enables the fluorescence data to be read out faster than would otherwise have been possible providing not only world leading spatial resolution, but also rate performance and energy resolution.

One of the first sets of nanoscale x-ray images taken at the HXN beamline in April 2015. Circular shapes correspond to nano-fabricated structures that are 20nm wide and 200nm tall.

“One of the first sets of nanoscale x-ray images taken at the HXN beamline in April 2015. These images were obtained by collecting fluorescence (platinum L-edge) x-rays that were emitted from a platinum resolution test pattern. The circular shapes correspond to nano-fabricated structures that are 20nm wide and 200nm tall. The colour scale indicates the fluorescence intensity over the acquisition period (200ms per pixel)”.

Several development efforts have been undertaken to assure the capabilities of the new HXN beamline, from pioneering concrete construction to a new class of multilayer Laue lenses. Quantum Detector’s Xspress 3 played a role in achieving the successful results shown below.

In addition to the Xspress 3, HXN have also taken delivery of a Zebra, V2F100 and Merlin detectors. Further details on these systems are available on their respective pages.
