Measurement of cosmic-ray low-energy antiproton spectrum with the first BESS-Polar Antarctic flight
K. Abe, H. Fuke, S. Haino +27
The BESS-Polar spectrometer had its first successful balloon flight over Antarctica in December 2004. During the 8.5-day long-duration flight, almost 0.9 billion events were record…
Measurements of 0.2 to 20 GeV/n cosmic-ray proton and helium spectra from 1997 through 2002 with the BESS spectrometer
Y. Shikaze, S. Haino, K. Abe +21
We measured low energy cosmic-ray proton and helium spectra in the kinetic energy range 0.215 - 21.5 GeV/n at different solar activities during a period from 1997 to 2002. The obse…
Simulation Studies of Delta-ray Backgrounds in a Compton-Scatter Transition Radiation Detector
John F. Krizmanic, Michael L. Cherry, Robert E. Streitmatter
In order to evaluate the response to cosmic-ray nuclei of a Compton-Scatter Transition Radiation Detector in the proposed ACCESS space-based mission, a hybrid Monte Carlo simulatio…
Development of Ground-testable Phase Fresnel Lenses in Silicon
John Krizmanic, Brian Morgan, Robert Streitmatter +5
Diffractive/refractive optics, such as Phase Fresnel Lenses (PFL's), offer the potential to achieve excellent imaging performance in the x-ray and gamma-ray photon regimes. In prin…
Measurements of Atmospheric Antiprotons
K. Yamato, K. Abe, H. Fuke +21
We measured atmospheric antiproton spectra in the energy range 0.2 to 3.4 GeV, at sea level and at balloon altitude in the atmospheric depth range 4.5 to 26 g/cm^2. The observed en…
Beam Test of a Prototype Detector Array for the PoGO Astronomical Hard X-Ray/Soft Gamma-Ray Polarimeter
T. Mizuno, T. Kamae, J. S. T. Ng +6
Polarization measurements in the X-ray and gamma-ray energy range can provide crucial information on massive compact objects such as black holes and neutron stars. The Polarized Ga…
