Workpackage NumberWorkpackage Description
1Manage the administrative, technical and financial terms of the project. Monitor compliance with the work of the overall project plans, the available resources and the timing. Create the necessary interface to the ERA-MIN services and other external stakeholders. Monitor the maintenance of the project web pages and use web-based project management tool. Ensure quality of the project results. Build requirement specifications.
2The X-ray imaging system is built according to the requirement specification defined in WP1.
The design parameters include at least the following: desired geometric magnification; tube target focus size requirement specification; width of the imaging area; possible TDI stage setup; possible collimation and radiation shielding; interesting energy thresholds.
An experimental system will be built according to the specs. Because ADC has specialised in low energy Si based detectors, they are usable for thinner material flows than the ones described in WP3, or the arrangement will be used that utilises the traditional scattered photon flux of XRF.
3The high energy X-ray imaging system is built according to the requirement specification defined in WP1. Ore will be responsible of the high voltage generator and X-ray tube setup building.
For the camera, the design parameters include similar ones as in WP2, with the difference that the use of the higher energy K lines is facilitated by both the X-ray generator by ORE and the compound semiconductor CdTe detector array by ADC. Since ADC has experience on the production of such detectors and detector arrays, the work consists by its modifications to the new application area in mining industry that is a new application area for ADC.
An experimental system will be built according to the specifications.
Design of 1x5 module camera hardware (photon counting energy discriminating CdTe Crystal Medipix row camera with active area of 70mmx14mm). Sensor control software, row camera calibration and GUI software are developed.
Manufacture and testing of (70mmx14mm) MAXI camera to be used under a conveyor belt. This is an experimental system compared to the compact detectors that ADC has delivered so far.
4The automated pre-enrichment system needs to have the controlling processed run on a real time operating system that is industrially adaptable. VTT has typically used the automation SW and HW by Beckhoff which is widely accepted in industry. In addition to the X-ray instrumentation, such a system needs to have 3D machine vision for localising the rock fragments running on the belt, as well as measuring their 3D shape which is needed for compensating the X-ray attenuation seen by the detector arrays. In addition the automation system has to have a teachable, easy to use human interface, and controllers for the mechanics, such as electric motors, and blowpipes performing the sorting. The automation system also makes the prototype demonstrator that is integrated in the project.
As a limited feasibility study, we will test matrix embedded Quantum dot (QD) fluorescent nanoparticles with a large Stokes shift for indirect detection of X-ray emission, using low readout noise sCMOS cameras.
5In order to get geophysically relevant results from the novel developments towards the X-ray analytics, we need to perform reference tests for the samples with existing laboratory equipment, including XRF, XRD, and possibly chemical or laser based instruments. Such facilities exist e.g. at the GIR Institute in Romania. Since the goal in the high energy developments include deep penetrating analysis, the samples have to be selected such that they do not have surface carrying interesting elements. If suitable samples are not available, they need to be prepared with artificial passive mineral covers. During the specification phase we will define the utilization of new samples from e.g. active Swedish and/or Finnish mining operators. GIR will use their contacts for managing industrially relevant samples for the use of the project.
