HX-POL - A Balloon-Borne Hard X-Ray Polarimeter (2008)
Krawczynski, H., Garson III, A., Li, Q., Beilicke, M., Dowkontt, P., Wulf, E., ...
We report on the design and estimated performance of a balloon-borne hard X-ray polarimeter called HX-POL. The experiment uses a combination of Si and Cadmium Zinc Telluride detectors to measure the...
EXIST's Gamma-Ray Burst Sensitivity (2007)
Band, D. L., Grindlay, J. E., Hong, J., Fishman, G., Hartmann, D. H., Garson III, A., ...
We use semi-analytic techniques to evaluate the burst sensitivity of designs for the EXIST hard X-ray survey mission. Applying these techniques to the mission design proposed for the Beyond Einstein...
Wide Field Hard X-ray Survey Telescope: ProtoEXIST1 (2007)
Hong, J., Grindlay, J. E., Chammas, N., Allen, B., Copete, A., Said, B., ...
We report our progress on the development of pixellated imaging CZT detector arrays for our first-generation balloon-borne wide-field hard X-ray (20 - 600 keV) telescope, ProtoEXIST1. Our ProtoEXIST...
CZT in Space Based Hard-X-ray Astronomy (2006)
Garson III, A., Krawczynski, H., Weidenspointner, G., Novikova, E. I., Grindlay, J., Hong, J., ...
One of the key aspects of a detector material for space-borne hard X-ray and gamma-ray telescopes is the rate of prompt and delayed background events generated inside the material by charged and...
Test of Thick Pixelated Orbotech Detectors with and without Steering Grids (2006)
Jung, I., Garson III, A., Krawczynski, H., Burger, A., Groza, M., Matteson, J., ...
We report here on the optimization of 0.5 cm thick pixelated Orbotech CZT detectors with regards to the best contacting materials and the use of steering grids. We evaluated the performance of...
Garson III, A., Krawczynski, H., Grindlay, J., Fishman, G. J., Wilson, C. A.
The Energetic X-ray Imaging Survey Telescope (EXIST) is a mission design concept that uses coded masks seen by Cadmium Zinc Telluride (CZT) detectors to register hard X-rays in the energy region from...
