MSc Project title
New technique of radiolabelling tracer with 64Cu for positron emission particle tracking (PEPT)
(Duration: Feb 2013 to Dec 2014)
Positron Emission Particle Tracking (PEPT) is a non-invasive technique used for obtaining direct information about the flow within industrial systems. It involves tracking the motion of a tracer particle labelled with a PET radionuclide using a Positron Emission Tomography (PET) camera. PEPT Cape Town, housed at iThemba LABS, hosts two PET cameras modified for PEPT and produced tracer particles for PEPT experiments on a daily basis. Read more...

Using PEPT to investigate the motion of granular material in a tumbling mill
(Supervisors: Dr I Govender, Dr AN Mainza, Prof J-P Franzidis)
Positron emission particle tracking (PEPT) is a radioactive imaging technique in which the products of β+ decay are used to triangulate the position of a representative - and suitably labelled - tracer particle in a bed of similar particles. Read more...
PhD Project title
The development of a simplified system for measuring the passage of particles on and through moving screen surfaces using discrete element modelling (DEM) and positron emission particle tracking (PEPT)
(Duration: April 2013 to Dec 2015)
Currently, the design and scale-up of screens still relies on rules of thumb and empirical factor methods. To go beyond the current state-of-the-art in screen modelling requires a clear understanding of the particle motion along a dynamic (vibrating) inclined plane. Read more...

MSc Project title
Optimization of the radio-labelling of ion exchange resin tracers for positron emission particle tracking
(Duration: Feb 2013 to Feb 2014)
Positron emission particle tracking (PEPT) is a technique which features the non-invasive tracking of tracer labelled with a β+ emitting radionuclide by detecting, using a PET scanner, the two nearly collinear 511 keV gamma rays resulting from the annihilations of the positrons. Read more...
