Experimental Particle and Astro-Particle Physics Seminar
Abstract:
This seminar focuses on investigating the origin, acceleration and propagation mechanisms of Cosmic Rays (CRs) in the Galaxy. These phenomena will be explored through the prism of space-borne detectors, specifically the Dark Matter Particle Explorer (DAMPE) and the High Energy cosmic-Radiation Detection (HERD) facility. DAMPE, is designed for precise CR studies in a wide energy range (up to hundreds of TeV), along with detailed measurements of high–energy gamma–rays and indirect searches of Dark Matter annihilation/decay to detectable particles. The satellite was successfully launched into a sun–synchronous orbit at 500 km, on December 17th 2015 and has been successfully acquiring data ever since. On the other hand, HERD is one of the prominent instruments to be installed onboard China's Space Station (CSS) around 2027. Its primary scientific goals include: precise measurements of CR energy spectra (individual nuclear species, secondary-over-primary-ratios and mass composition) at energies from a few tens of GeV up to a few PeV, electron plus positron spectra up to tens of TeV, CR anisotropy, gamma ray astronomy, along with indirect searches for Dark Matter. HERD is uniquely configured to accept particles from both its top and four lateral sides. Owing to its pioneering design, an order of magnitude increase in geometric acceptance is foreseen, compared to current generation experiments. A detailed overview of the latest DAMPE results and scientific objectives of HERD will be presented, with emphasis on current analyses and optimization efforts along with a glimpse on future activities.
