Project: Mineral Analysis using X-ray Imaging

Acronym	MAXI
Duration	01/01/2014 - 31/12/2016
Project Topic	The main objective of the research is to improve material analysis efficiency, both in terms of material recognition accuracy and speed of detection. XRF spectroscopy is widely used in production plants and exploration of mining companies, both as handheld instruments and in conveyor belt analysis subsystems. However, current industrial XRF systems have poor spatial resolution: they typically are unable to localize particles with dimensions below 100mm. The goal of the project is to improve the selectivity at least with one order of magnitude, down to about 10mm spatial resolution. Another shortage of current industrial XRF systems is the fact that they only analyse the surface of the sample, ignoring most of the volume. This gives an erroneous estimate of the element concentration, especially for elements with uneven distribution, such as precious metals. The goal here is to read XRF-signals from the whole sample volume by using high energy X-ray generators and detector arrays.
