Abstract

The project goals are: (1) Develop CMT radiation detectors - Demonstrate feasibility (Phase 1 is complete) and Improve material properties and device performance; (2) This project will lead to novel radiation detectors - high detection efficiency, high energy-resolution, ambient-temperature operation, and low production cost; and (3) Such detectors are needed in areas of nonproliferation and national security for detection of SNM. Research highlights are: (1) We achieved our Phase-I goal - Demonstration of CMT detector performance approaching that of CZT detectors; (2) Demonstrated that In-doped CMT is much closer to its anticipated performance as radiation detectors than other alternative materials, TlBr and HgI{sub 2} - Large crystal volumes, 10{sup 10}{Omega}{center_dot}cm, 3 x 10{sup -3}cm{sup 2}/V, and stable response; and (3) Conducted material and device characterization experiments - Detectors: I-V, {mu}{sub e}, ({mu}{tau}){sub e}, internal E fields, energy spectra, and high-resolution x-ray response mapping data and Materials - DLTS, TCT, PL, EPDs, XRD, PCD and IR transmission.

Proceedings of the symposium on Nuclear Radiation Detection Materials

Conference Perry, D; Burger, A; Franks, L; ...

This symposium provides a venue for the presentation of the latest results and discussion of radiation detection materials from both experimental and theoretical standpoints. As advances are made in this area of materials, additional experimental and theoretical approaches are used to both guide the growth of materials and to characterize the materials that have a wide array of applications for detecting different types of radiation. The types of detector materials for semiconductors and scintillators include a variety of molecular compounds such as lanthanum halides (LaX{sub 3}), zinc oxide (ZnO), lead iodide (PbI{sub 2}), cadmium telluride (CdTe), mercuric iodide (HgI{sub 2}),more »« less
Optimized performance for neutron interrogation to detect SNM

Technical Report Slaughter, D; Asztalos, S; Biltoft, P; ...

A program of simulations and validating experiments was utilized to evaluate a concept for neutron interrogation of commercial cargo containers that would reliably detect special nuclear material (SNM). The goals were to develop an interrogation system capable of detecting a 5 kg solid sphere of high-enriched uranium (HEU) even when deeply embedded in commercial cargo. Performance goals included a minimum detection probability, P{sub d} {ge} 95%, a maximum occurrence of false positive indications, P{sub fA} {le} 0.001, and maximum scan duration of t {le} 1 min. The conditions necessary to meet these goals were demonstrated in experimental measurements even whenmore »« less

Defect Levels of Indium-doped CdMnTe Crystals

Journal Article Kim, K; Bolotinikov, A; Camarda, G; ... - Journal of Applied Physics

Using photoluminescence (PL) and current deep-level transient spectroscopy (I-DLTS), we investigated the electronic defects of indium-doped detector-grade CdMnTe:In (CMT:In) crystals grown by the vertical Bridgman method. We similarly analyzed CdZnTe:In (CZT:In) and undoped CdMnTe (CMT) crystals grown under the amount of same level of excess Te and/or indium doping level to detail the fundamental properties of the electronic defect structure more readily. Extended defects, existing in all the samples, were revealed by synchrotron white beam x-ray diffraction topography and scanning electron microscopy. The electronic structure of CMT is very similar to that of CZT, with shallow traps, A-centers, Cd vacancies,more »« less

SNM Movement Detection/Radiation Sensors and Advanced Materials Portfolio Review

Conference James, R

The project objectives are: (1) determine for the first time the properties limiting the performance of CZT detectors; (2) develop efficient, non-destructive techniques to measure the quality of detector materials; and (3) provide rapid feedback to crystal growers and, in conjunction with suppliers, improve CZT detector performance as measured by device energy resolution, efficiency, stability and cost. The goal is a stable commercial supply of low-cost, high energy resolution (0.5% FWHM at 662 keV) CZT crystals for detecting, characterizing and imaging nuclear and radiological materials in a wide variety of field conditions.

Cesium lead bromide semiconductor radiation detectors: crystal growth, detector performance and polarization

Journal Article Toufanian, Reyhaneh; Swain, Santosh; Becla, Piotr; ... - Journal of Materials Chemistry C

Cesium lead bromide (CsPbBr₃) is an upcoming semiconductor radiation detector that has the potential to match the detection properties of cadmium zinc telluride (CZT) and thallium bromide (TlBr). In this paper, we report on CsPbBr₃ gamma detectors with an uncorrected energy resolution of 2% at 662 keV with photopeak-to-Compton ratios as high as 14.3 and hole mobility-lifetime products (μτ_h) as high as 1.7 × 10^–2 cm² V^–1. Furthermore, we demonstrate that the processes employed for material purification and crystal growth of high-performing devices are scalable, and large (up to 65 mm in diameter) ultrahigh purity CsPbBr₃ crystals have been successfullymore »« less
