Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics, shares his UFS journey.

The University of the Free State (UFS) is celebrating Youth Month by showcasing the positive influence of the institution on career development. As part of this initiative, we are sharing the stories of UFS alumni who are now working at the university.

Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics, shares his UFS journey:

Q: Year of graduation from the UFS: 

A: 2004 and 2015.

Q: Qualification obtained from the UFS: 

A: BSc in Physics and Mathematics and PhD in Solid State Physics.

Q: Date of joining the UFS as a staff member: 

A: 2003 to 2004 and 2012 to date.

Q: Initial job title and current job title: 

A: I began my journey as a Lab Assistant, but over time, I advanced to higher positions within the academic realm. Presently, I proudly serve as a Senior Lecturer and Subject Head in the esteemed Department of Physics. Additionally, I have taken on the role of acting Assistant Dean in the distinguished Faculty of Natural and Agricultural Sciences.

Q: How did the UFS prepare you for the professional world? 

A: First and foremost, I successfully completed my BSc degree, followed by the attainment of a Doctor of Philosophy (PhD). I firmly believe that these educational achievements serve as a solid foundation for excelling in both teaching and leadership roles.

Q: What are your thoughts on transitioning from a UFS alumnus to a staff member? 

A: It is a very interesting aspect; however, this transition may entirely depend on an individual’s interest in whether to continue with their studies or not. The stimulation may come from the undergraduate teachings that exhibit real interventions for new developments towards empowering the society at large.

Q: Any additional comments about your experience? 
A: As both an academic and a departmental leader for the past nine years, I am very grateful for all the support from the university community. I would encourage young scholars to explore more leadership roles that are available in the sector, because one is always up to date with new initiatives and strategies for the betterment of human and academic projects.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.

Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.

The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).

According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.

In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.

“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.

H.E.S.S. has issued a complete statement about the paper published in Nature.
