Building 203, Room R150
iThemba LABS is a home to the Separated Sector Cyclotron which is the most powerful accelerator in the southern hemisphere. This cyclotron produces beams ranging from heavy to light ions up to a maximum energy of 200 MeV. The heavy ion projectiles emit gamma-rays which are being detected using the AFRican Omnipurpose Detector for Innovative Technologies and Experiments (AFRODITE).

AFRODITE is a medium size array that has the unique capability of detecting both high and low energy photons with a reasonably high efficiency by combining large volume escape suppressed HPGe detectors (CLOVERS) with Low Energy Photon Spectrometer (LEPS) detectors. There also exists a state-of-the-art K600 Magnetic Spectrometer which is a unique facility world-wide for the study of nuclear structure and reaction mechanisms at intermediate energies using light-ion projectiles. In particular, high energy-resolution experiments on nuclei in the region of giant resonances present a powerful tool to extract information about the dominant processes leading to equilibration. Other experiments include the alpha and 3HE d reactions for the investigation of the Hoyle state in 12C and p, t for characterisation of cluster states in 16O with nuclear astrophysics applications. Experimental results, recent upgrades and future research program in maximising the capability of these unique facilities will be presented.
