Research Activities | ||||
Space Radiation Environment & Effects | Study and simulation of the radiation environment in the heliosphere: radiation monitoring and effects on EEE components | |||
Pierre Auger Observatory | The Pierre Auger Cosmic Ray Observatory is studying ultra-high energy cosmic rays, the most energetic and rarest of particles in the universe. When these particles strike the earth's atmosphere, they produce extensive air showers made of billions of secondary particles. While much progress has been made in nearly a century of research in understanding cosmic rays with low to moderate energies, those with extremely high energies remain mysterious. The Pierre Auger Observatory is working on solving these mysteries. | |||
| ||||
Geant4 collaboration | Geant4 is a toolkit for the simulation of the passage of particles through matter. Its areas of application include high energy, nuclear and accelerator physics, as well as studies in medical and space science. | |||
