High-throughput MeV ion beam analysis − quantitative full stoichiometry imaging of a granite

MeV Ion-Beam analysis (IBA) can quantify the whole periodic table, provide tomographic information, analyse elements up to 100 µm depth, and achieve down to nm depth resolution under ideal conditions. This brings along a high degree of instrument and data analysis complexity. Only recently, optimised instrument geometry and precision on the hardware-side and artificial intelligence, modern computing power, and new nuclear cross-sections on the software-side enabled analysing the IBA spectra effectively and with only little human interaction. The increased throughput reinvents IBA as an elemental imaging technology. This work presents a 5x5mm 2 imaging of a granite sample with 100x100 pixels using four IBA methods measured and analysed within 24 h. This demonstrates the capabilities of the newly developed software and hardware solutions. The analysis reveals SiO 2 , an Al, and a Fe rich phases in the granite. The present elements and their concentrations match typical granite phases.
