Abstract

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 10Be from ∼0.2 GeV/n to beyond 3 GeV/n, will provide essential insights into the propagation processes of the cosmic rays. HELIX features a Ring Imaging Cherenkov (RICH) detector designed to measure the velocity and charge of nuclei with energies greater than ∼1 GeV/n. The RICH detector consists of a radiator volume of high-transparency high-index aerogel tiles imaged by a ∼1 m2 focal plane instrumented by 200 8×8 arrays of silicon photomultipliers (SiPMs). A scintillating fiber hodoscope read out with SiPM arrays is installed on the top of the RICH radiator plane to improve the accuracy of track reconstruction in the non-bending view of the instrument’s magnet spectrometer system. We present the design and current status of the HELIX RICH and hodoscope systems.
