Phase Fresnel Lens Development for X-ray and Gamma-ray Astronomy

Autor: Krizmanic, John, Skinner, Gerald, Arzoumanian, Zaven, Badilita, Vlad, Gehrels, Neil, Gendreau, Keith, Ghodssi, Reza, Gorius, Nicolas, Morgan, Brian, Mosher, Lance, Streitmatter, Robert

In principle, diffractive optics, particularly Phase Fresnel Lenses (PFLs), offer the ability to construct large, diffraction-limited, and highly efficient X-ray/$\gamma$-ray telescopes, leading to dramatic improvement in angular resolution and photo

Report

Optimization of the Orbiting Wide-angle Light Collectors (OWL) Mission for Charged-Particle and Neutrino Astronomy

Autor: Krizmanic, John F., Mitchell, John W., Streitmatter, Robert E.

OWL uses the Earth's atmosphere as a vast calorimeter to fully enable the emerging field of charged-particle astronomy with high-statistics measurements of ultra-high-energy cosmic rays (UHECR) and a search for sources of UHE neutrinos and photons. C

Simulation Studies of Delta-ray Backgrounds in a Compton-Scatter Transition Radiation Detector

Autor: Krizmanic, John F., Cherry, Michael L., Streitmatter, Robert E.

Publikováno v: Nucl.Instrum.Meth. A563 (2006) 303-305

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 simulation using GEANT3 and an external transition radiation (TR) generator rou

Development of Ground-testable Phase Fresnel Lenses in Silicon

Autor: Krizmanic, John, Morgan, Brian, Streitmatter, Robert, Gehrels, Neil, Gendreau, Keith, Arzoumanian, Zaven, Ghodssi, Reza, Skinner, Gerry

Publikováno v: Exper.Astron.20:299-306,2005

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 principle, the angular resolution obtained with these devices can be diffr

Report

Limitations on Space-based Air Fluorescence Detector Apertures obtained from IR Cloud Measurements

Autor: Krizmanic, John, Sokolsky, Pierre, Streitmatter, Robert

The presence of clouds between an airshower and a space-based detector can dramatically alter the measured signal characteristics due to absorption and scattering of the photonic signals. Furthermore, knowledge of the cloud cover in the observed atmo
