Description
HELIX is a balloon-borne experiment designed to measure the chemical and isotopic abundances of light cosmic-ray nuclei from protons up to neon with event-by-event mass resolution better than 3 %. Through a multi-staged payload approach, HELIX aims to measure the propagation of the clock isotope 10^Be over the energy range from 0.1 GeV/n to 10 GeV/n. These measurements will contribute to improving our understanding of Galactic cosmic-ray propagation, which is timely given multi-messenger observations of the diffuse high-energy gamma-ray and neutrino emission from the Galactic plane. HELIX had its first engineering flight in the summer of 2024, which lasted about 7 days. In this talk, I will give an update on the status of ongoing analysis efforts as well as the detector refurbishment and development for the next flight.
