A facility dedicated to Positron Emission Particle Tracking (PEPT) at the University of Cape Town
What is PEPT
PEPT is a technique used to non-invasively measure particle behaviour in flowing and granular systems and can track a tracer particle moving at speeds of up to 10 m/s to location uncertainties lower than 1 mm.
We house two PET scanners: a Siemens ECAT HR++ PET scanner, with high efficiency and spatial resolution, and an ADAC Vertex, with large field of view to accommodate larger experiments.
In our tracer fabrication laboratory, we fabricate tracer particles labelled with the PET radionuclides 68Ga and 18F with controllable physical properties such as size, shape, and density and controllable chemical properties such as hydrophobicity.
The kinematic and residence time data from the motion of a tracer particle can offer insight into the efficiency of industrial processes and provide experimental data to validate fundamentally based models. Recent applications that have benefited from PEPT measurements include mineral processing, petroleum geology, and mixing. We investigate the fundamental behaviour of dynamic processes, and often make measurements of systems with harsh conditions such as high pressures, temperatures, shear rates, and dense multi-phase slurries.

PEPT Cape Town was opened on the 4th August 2009 to over 200 guests. Find out more about our friends and collaborators, without whose support PEPT Cape Town wouldn’t be here today.
