Developing a silica aerogel radiator for the HELIX ring-imaging Cherenkov system
Makoto Tabata, Patrick Allison, James J. Beatty +18
This paper reports the successful fabrication of silica aerogel Cherenkov radiators produced in the first batches from a 96-tile mass production performed using pin-drying techniqu…
Sub-Pixel Response Measurement of Near-Infrared Sensors
N. Barron, M. Borysow, K. Beyerlein +6
Wide-field survey instruments are used to efficiently observe large regions of the sky. To achieve the necessary field of view, and to provide a higher signal-to-noise ratio for fa…
New Measurement of the Cosmic-Ray Positron Fraction from 5 to 15 GeV
J. J. Beatty, A. Bhattacharyya, C. Bower +12
We present a new measurement of the cosmic-ray positron fraction at energies between 5 and 15 GeV with the balloon-borne HEAT-pbar instrument in the spring of 2000. The data presen…
A new measurement of the altitude dependence of the atmospheric muon intensity
J. J. Beatty, S. Coutu, S. A. Minnick +12
We present a new measurement of atmospheric muons made during an ascent of the High Energy Antimatter Telescope balloon experiment. The muon charge ratio mu+/mu- as a function of a…
Supernova / Acceleration Probe: A Satellite Experiment to Study the Nature of the Dark Energy
SNAP Collaboration, G. Aldering, W. Althouse +109
The Supernova / Acceleration Probe (SNAP) is a proposed space-based experiment designed to study the dark energy and alternative explanations of the acceleration of the Universe's…
Wide-Field Surveys from the SNAP Mission
A. Kim
The Supernova/Acceleration Probe (SNAP) is a proposed space-borne observatory that will survey the sky with a wide-field optical/near-infrared (NIR) imager. The images produced by…
