Thick CZT Detectors for Space-Borne X-ray Astronomy
H. Krawczynski, I. Jung, J. Perkins +2
Cadmium Zinc Telluride (CZT) detectors are having a major impact on the field of hard X-ray astronomy. Without the need for cryogenic cooling they achieve good spatial and energy r…
Direct comparison of the performance of CZT detectors contacted with various metals
I. Jung, M. Groza, J. Perkins +2
Cadmium Zinc Telluride (CZT) achieves excellent spatial resolution and good energy resolution over the broad energy range from several keV into the MeV energy range. In this paper…
Scintillation properties of SrI_2(Eu^2+) (Strontium iodide doped with europium) for high energy astrophysical detectors: Nonproportionality as a function of temperature and at high gamma-ray energies
R. S. Perea, A. M. Parsons, M. Groza +5
Strontium iodide doped with europium is a new scintillator material being developed as an alternative to lanthanum bromide doped with cerium for use in high energy astrophysical de…
Thick Pixelated CZT Detectors With Isolated Steering Grids
I. Jung, A. B. Garson, J. S. Perkins +5
We explore the possibility to improve the performance of 0.5 cm thick Cadmium Zinc Telluride (CZT) detectors with the help of steering grids on the anode side of the detectors. Ste…
Detailed Studies of Pixelated CZT Detectors Grown with the Modified Horizontal Bridgman Method
I. Jung, H. Krawczynski, A. Burger +2
The detector material Cadmium Zinc Telluride (CZT), known for its high resolution over a broad energy range, is produced mainly by two methods: the Modified High-Pressure Bridgman…
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…
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…
