The High Energy Light Isotope eXperiment program of direct cosmic-ray studies
HELIX Collaboration, S. Coutu, P. S. Allison +27
HELIX is a new NASA-sponsored instrument aimed at measuring the spectra and composition of light cosmic-ray isotopes from hydrogen to neon nuclei, in particular the clock isotopes…
Electron-beam Calibration of Aerogel Tiles for the HELIX RICH Detector
P. Allison, M. Baiocchi, J. J. Beatty +21
The HELIX cosmic-ray detector is a balloon-borne instrument designed to measure the flux of light isotopes in the energy range from 0.2 GeV/n to beyond 3 GeV/n. It will rely on a r…
Trigger system for the Payload for Ultrahigh Energy Observations (PUEO) balloon-borne neutrino detector
Q. Abarr, J. Alfaro, P. Allison +67
The Payload for Ultrahigh Energy Observations (PUEO) is a NASA balloon-borne instrument for the detection of ultra-high energy (UHE) neutrinos with energies above $10^{17.5}~\textr…
The High-Energy Light Isotope eXperiment (HELIX) Instrument
P. S. Allison, M. Baiocchi, J. J. Beatty +27
The HELIX detector is a balloon-borne instrument designed to measure the flux of light (Z < 11) cosmic-ray isotopes. In this paper we describe the initial configuration of HELIX, o…
The Dark Energy Camera
B. Flaugher, H. T. Diehl, K. Honscheid +115
The Dark Energy Camera is a new imager with a 2.2-degree diameter field of view mounted at the prime focus of the Victor M. Blanco 4-meter telescope on Cerro Tololo near La Serena,…
