The ASP has evolved to be much more than a school. It is a program of actions with directed ethos toward physics as an engine for development in Africa.

Photons and Neutrons in the quest to solve societal challenges


Research Infrastructures like Light Sources and Neutrons Sources are perfect tools for discoveries, e.g. COVID-19 structure, battery materials. 


In this second ASP lecture serie, we focus on the description of such infrastructures and the power of photons and neutrons.

“The power of photon and neutron, gathering Research Infrastructures and education, in the quest to solve societal challenges” 


Certain experimental analytic facilities are too large and expensive to be set up by individual research groups or universities and are instead established and supported at national or international level. Among such national facilities, those for synchrotron radiation and neutron scattering are particularly useful for the study of the structure, chemical composition, dynamics and magnetic and electronic properties of materials. This course first outlines the principles of interaction of powerful X-rays with materials and describes how these principles may then be exploited in crystallography and chemical analysis with information on valence states and local chemical environment at sub-micron resolution. Neutrons provide a complementary probe that is particularly sensitive and informative about light elements such as hydrogen, about magnetic structure and about atomic and molecular motion relevant to chemical diffusion and magnetic excitations.
