“…Other ongoing analyses are currently studying individual spectra of B, C and O [34] as well as other CR species, from the secondaries Li, Be to heavier primaries such as Ne, Mg, Si up to Fe [35]. High background contamination and fragmentation inside the detector make such measurements challenging.…”

The space-based DAMPE (DArk Matter Particle Explorer) particle detector has been taking data for more than 6 years since its successful launch in December 2015. Its main scientific goals include the indirect search of Dark Matter signatures in the cosmic lepton spectra, the study of Galactic Cosmic Rays up to energies of hundreds of TeV and high-energy gamma ray astronomy. This talk will focus on Galactic Cosmic Rays and the measurement of their spectra, fundamental to investigate the mechanisms of acceleration at their sources and propagation through the interstellar medium. The most recent results on Proton and Helium, which revealed new spectral features, will be highlighted. Ongoing analyses regarding the cosmic ray light component, medium and heavy mass nuclei will be discussed alongside studies on the so-called secondary cosmic rays.

The DArk Matter Particle Explorer (DAMPE) is a space-based particle detector launched on December 2015 from the Jiuquan Satellite Launch Center in China, and since then smoothly operating in a Sun-synchronous orbit. The main goals of the DAMPE mission include the study of the Cosmic-Ray Electron-positron (CRE) energy spectrum, the study of galactic cosmic-rays (CR), gamma-ray astronomy, and indirect dark matter search. The large acceptance and the detector figures make DAMPE able to measure the CREs and gamma-rays spectra up to few TeV, and cosmic-ray nuclei spectra up to hundreds of TeV, with unprecedented statistics and resolutions. An overview of the DAMPE mission will be presented, along with main results and ongoing activities, focusing on CR spectral measurements. *** 27th European Cosmic Ray Symposium -ECRS *** *** 25-29 July 2022 *** *** Nĳmegen, the Netherlands *** * Speaker

DAMPE (Dark Matter Particle Explorer) is a satellite-born experiment launched in 2015 in a sun-synchronous orbit at 500 km altitude, and it has been taking data in stable conditions ever since. Its main goals include the spectral measurements up to very high energies, cosmic electrons/positrons and gamma rays up to tens of TeV, and protons and nuclei up to hundreds of TeV. The detector’s main features include the 32 radiation lengths deep calorimeter and large geometric acceptance, making DAMPE one of the most powerful space instruments in operation, covering with high statistics and small systematics the high energy frontier up to several hundreds TeV. The results of spectral measurements of different species are shown and discussed.
