Nano to begin drilling next week in Illinois
It’s been a good month for Nano Nuclear in the state of Illinois. On October 7, the Office of Governor J.B. Pritzker announced that the company would be awarded $6.8 million from the Reimagining Energy and Vehicles in Illinois Act to help fund the development of its new regional research and development facility in the Chicago suburb of Oak Brook.

Three-dimensional (3-D) computed micro X-ray tomography (micro CT) and 3-D confocal micro X-ray fluorescence (MXRF) combined are very useful nondestructive metrology techniques for determining the unique compositional and morphological information of fusion targets and target materials. Micro CT and confocal MXRF are being used in concert to examine a beryllium ablator capsule that has been sputtered and graded doped with copper and argon. In this manuscript, we will show that two-dimensional (2-D) MXRF imaging in concert with a simple radiograph is very useful for approximating the copper and argon profiles in the x and y dimensions, but because of the lack of signal discrimination in the z direction, image "bleed" from the sample regions where the X-rays are out of focus is prevalent. Data collected using the micro CT and overlapped with the confocal MXRF data produce absorbance and elemental line profiles without the signal bleed. Overlapping the 3-D data from these techniques provides a more accurate picture of the composition of these capsules than 2-D nondestructive techniques.
