Cosmic-ray isotope measurements with HELIX
HELIX (High Energy Light Isotope eXperiment) is a balloon-borne experiment designed to measure the chemical and isotopic abundances of light cosmic-ray nuclei. Detailed measurements by HELIX, especially of long-lived nuclei, Be-10, in an energy range from ∼0.2 GeV/n to beyond 10 GeV/n, will provide essential insights into the propagation processes of cosmic rays in the Galaxy. A high-precision drift chamber tracker in a 1 T superconducting magne
t is used for magnetic rigidity measurements and time-of-flight scintillator paddles and an aerogel-based ring-imaging Cherenkov detector are designed to measure charges and velocities at different energy ranges. The first Arctic flight of HELIX from Northern Sweden was successfully conducted this summer. I will present an overview and current status of the HELIX.
