Rapporteur ICRC 2021: Neutrinos and Muons

Rapporteur Talk: Cosmic Ray Direct

“…10 Be/ 9 Be, have significantly extended the energy reach and precision over previous measurements. Most interestingly, 10 Be/ 9 Be remains almost constant and close to 0.2 between 1 and 10 GeV/n and no sharp upturn is observed, which should point to a rather large height of the CR halo. Apart from the scientific significance, this analysis stands out since not only errors but also correlation matrices are provided.…”

“…The measurements of the isotopic ratios, e.g. 10 Be/ 9 Be, have significantly extended the energy reach and precision over previous measurements. Most interestingly, 10 Be/ 9 Be remains almost constant and close to 0.2 between 1 and 10 GeV/n and no sharp upturn is observed, which should point to a rather large height of the CR halo.…”

“…Therefore, the relative abundances must be determined by fitting templates to the observational mass distributions in the individual energy bins. A careful analysis has enabled the measurements of 6 Li and 7 Li and fluxes between 0.3 and 11 GeV/n and of 7 Be, 9 Be and 11 Be between 0.5 and…”

“…the Beryllium ratio. It consists of a drift chamber tracker, a time-of-flight system and a ring imaging Cherenkov counter and, given it large size and field of view, it will be able to achieve unprecedentedly small errors on 9 Be/ 10 Be in a matter of days. It is planned to fly in 2022 already.…”
