41. Expanding PEPT applications with tracer techniques

Michael van Heerden (University of Cape Town)

Oral

Positron emission particle tracking (PEPT) is a non-invasive tracking technique best used in understanding the fundamental physics within opaque multiphase flow systems. This dedicated research facility is situated within iThemba LABS and requires accurate and representative tracers to mimic the behaviour of the material of interest for a system under study. This presentation divulges the...

27. Measurements and signal processing of energy and time signals of 22Na using LaBr3:Ce scintillation detectors

Storm Johnson (University of Cape Town)

Positronium (Ps) is a system consisting of an electron and its anti-particle, a positron, bound together into an exotic atom, specifically an onium. The system is unstable: the two particles annihilate each other to predominantly produce two or three gamma-rays, depending on the relative spin states. Even rarer decays (with branching ratios <10$^{-6}$) can be detected with a suitable array of...

64. Monte Carlo Simulations of the iThemba LABS Neutron Beam Facility

Dr Zina Ndabeni (UCT/iThemba LABS )

Oral

iThemba LABS fast neutron beam facility (D-line vault) is one of the two facilities in the world that can provide quasi mono-energetic neutron beams in the energy from about 30 MeV to 200 MeV. The vault is currently undergoing an upgrade and development in order for it to meet the requirements for a medium and high-energy neutron metrology facility. One of the major challenges identified from...

37. Sub-Millimetre Positron-Emission Particle Tracking using a CdZnTe Semiconductor Array

Nicholas Hyslop

The Positron Emission Particle Tracking (PEPT) technique has been in development in Cape Town since 2009, and allows one to track a 1mm positron-emitting point source travelling at 1m/s to within 1mm, 1000 times a second. Traditionally, this utilises large scintillation Bismuth Germanium Oxide (BGO) arrays, which offer high intrinsic efficiency at 511keV (60-65\%) but low spatial resolution...
