Pierre Auger Observatory


The AugerPrime-Symposium will be held at Malargüe, Province of Mendoza (Argentina) from Nov. 14 - 17, 2015. Besides tours and presentations of the Pierre Auger Observatory there will be the Inauguration of AugerPrime with the signing ceremony of the International Agreement.

AugerPrime Upgrade
Auger data indicate that the most energetic particles are not only protons but mostly heavy, highly-charged, nuclei. These are deflected by cosmic magnetic fields, which makes it difficult to track back to their origin. The AugerPrime upgrade-endeavour addresses this challenge with dedicated instrumental upgrades. Another ten years of operation is expected to double the data set and to identify the cosmic accelerators. The original cosmic rays will be inferred by getting more details about the mixture of secondary air-shower particles. This will also include the exploration of fundamental particle physics at energies beyond those accessible at terrestrial accelerators, and the observation of new physics phenomena.

The key element of the upgrade will be the installation of a plastic scintillator on top of each existing surface detector stations. It will provide a complementary measurement of the showers allowing the reconstruction of muons and electromagnetic particles. The surface scintillator detector stations (SSD) will be deployed over the full 3,000-km2 area of the overall surface detector (SD).
