HX-POL - A Balloon-Borne Hard X-Ray Polarimeter
H. Krawczynski, A. Garson, Q. Li +10
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 detect…
Fabrication and Test of Pixelated CZT Detectors with Different Pixel Pitches and Thicknesses
Q. Li, A. Garson, P. Dowkontt +8
The main methods grown Cadmium Zinc Telluride (CZT) crystals with high yield and excellent homogeneity are Modified Horizontal Bridgman (MHB) and High Pressure Bridgman (HPB) proce…
Test of CZT Detectors with Different Pixel Pitches and Thicknesses
Qiang Li, Alfred III Garson, Ira Jung +6
The Modified Horizontal Bridgman (MHB) process produces Cadmium Zinc Telluride (CZT) crystals with high yield and excellent homogeneity. Various groups,including our own, previousl…
CZT in Space Based Hard-X-ray Astronomy
A. Garson, H. Krawczynski, G. Weidenspointner +4
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…
Test of Thick Pixelated Orbotech Detectors with and without Steering Grids
I. Jung, A. Garson, H. Krawczynski +4
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 pe…
Using the Active Collimator and Shield Assembly of an EXIST-Type Mission as a Gamma-Ray Burst Spectrometer
A. Garson, H. Krawczynski, J. Grindlay +2
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…
