Experimental limitations of coded aperture imaging using thick 3D-position-sensitive CdZnTe detectors
2010 Edition, October 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

3D-position-sensitive detectors have demonstrated Compton imaging and excellent energy resolution at room-temperature operation. Unfortunately, Compton imaging is not practical at gamma-ray energies below 300keV in CdZnTe detectors, due to the...

Time-Encoded Gamma-Ray Imaging Using a 3D-Position-Sensitive CdZnTe Detector Array
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The gamma-ray response of thick pixelated CdZnTe detectors varies spatially but is relatively constant as a function of time. Detector irregularities arise from flaws in the material, electrode fabrication, and gaps between detectors in an array. These nonuniformities...

Low background measurements using 3-D position-sensitive CdZnTe detectors
2013 Edition, October 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

There are numerous applications for CdZnTe detectors that require a well characterized background. One such application is the study of neutrino-less double beta decay, which requires a very low background environment. The background has two main contributors, the natural background...
