Available in PDF, EPUB and Kindle. Book excerpt: There is a need in many fields, such as nuclear medicine, non-proliferation, energy exploration, national security, homeland security, nuclear energy, etc, for miniature, thermal neutron detectors. Until recently, thermal neutron detection has required physically large devices to provide sufficient neutron interaction and transduction signal. Miniaturization would allow broader use in the fields just mentioned and open up other applications potentially. Recent research shows promise in creating smaller neutron detectors through the combination of high-neutron-cross-section converter materials and solid-state devices. Yet, till recently it is difficult to measure low neutron fluxes by solidstate means given the need for optimized converter materials (purity, chemical composition and thickness) and a lack of designs capable of efficient transduction of the neutron conversion products (x-rays, electrons, gamma rays). Gadolinium-based semiconductor heterojunctions have detected electrons produced by Gd-neutron reactions but only at high neutron fluxes. One of the main limitations to this type of approach is the use of thin converter layers and the inability to utilize all the conversion products. In this LDRD we have optimized the converter material thickness and chemical composition to improve capture of conversion electrons and have detected thermal neutrons with high fidelity at low flux. We are also examining different semiconductor materials and converter materials to attempt to capture a greater percentage of the conversion electrons, both low and higher energy varieties. We have studied detector size and bias scaling, and cross-sensitivity to xrays and shown that we can detect low fluxes of thermal neutrons in less than 30 minutes with high selectivity by our approach. We are currently studying improvements in performance with direct placement of the Gd converter on the detector. The advancement of sensitive, miniature neutron detectors will have benefits in energy production, nonproliferation and medicine.

Available in PDF, EPUB and Kindle. Book excerpt: In this work novel solid-state neutron detectors based on Gallium Nitride (GaN) have been produced and characterized. GaN is a radiation hard semiconductor which is commonly used in commercial optoelectronic devices. The important design consideration for producing GaN-based neutron detectors have been examined, and device simulations performed. Scintillators and p-i-n diode-type neutron detectors have been grown by metalorganic chemical vapor deposition (MOCVD) and characterized. GaN was found to be intrinsically neutron sensitive through the Nitrogen-14 (n, p) reaction. Neutron conversion layers which produce secondary ionizing radiation were also produced and evaluated. GaN scintillator response was found to scale highly linearly with nuclear reactor power, indicating that GaN-based detectors are suitable for use in the nuclear power industry. This work is the first demonstration of using GaN for neutron detection. This is a novel application for a mature semiconductor material. The results presented here provide a proof-of-concept for solid-state GaN-based neutron detectors which offer many potential advantages over the current state-of-the-art, including lower cost, lower power operation, and mechanical robustness. At present Helium-3 proportional counters are the preferred technology for neutron detection, however this isotope is extremely rare, and there is a global shortage. Meanwhile demand for neutron detectors from the nuclear power, particle physics, and homeland security sectors requires development of novel neutron detectors which are which are functional, cost-effective, and deployable.

Book Synopsis Radiation Detection by : Douglas McGregor
Download or read book Radiation Detection written by Douglas McGregor and published by CRC Press. This book was released on 2020-08-19 with total page 1286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation Detection: Concepts, Methods, and Devices provides a modern overview of radiation detection devices and radiation measurement methods. The book topics have been selected on the basis of the authors’ many years of experience designing radiation detectors and teaching radiation detection and measurement in a classroom environment. This book is designed to give the reader more than a glimpse at radiation detection devices and a few packaged equations. Rather it seeks to provide an understanding that allows the reader to choose the appropriate detection technology for a particular application, to design detectors, and to competently perform radiation measurements. The authors describe assumptions used to derive frequently encountered equations used in radiation detection and measurement, thereby providing insight when and when not to apply the many approaches used in different aspects of radiation detection. Detailed in many of the chapters are specific aspects of radiation detectors, including comprehensive reviews of the historical development and current state of each topic. Such a review necessarily entails citations to many of the important discoveries, providing a resource to find quickly additional and more detailed information. This book generally has five main themes: Physics and Electrostatics needed to Design Radiation Detectors Properties and Design of Common Radiation Detectors Description and Modeling of the Different Types of Radiation Detectors Radiation Measurements and Subsequent Analysis Introductory Electronics Used for Radiation Detectors Topics covered include atomic and nuclear physics, radiation interactions, sources of radiation, and background radiation. Detector operation is addressed with chapters on radiation counting statistics, radiation source and detector effects, electrostatics for signal generation, solid-state and semiconductor physics, background radiations, and radiation counting and spectroscopy. Detectors for gamma-rays, charged-particles, and neutrons are detailed in chapters on gas-filled, scintillator, semiconductor, thermoluminescence and optically stimulated luminescence, photographic film, and a variety of other detection devices.

Book Synopsis The Development of a Novel Diamond-based Neutron Detector and Quantum Color Center Fabrication Framework by : Henry Matthew Thurston

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work investigates the use of single crystal diamond in sensing technologies. First, homoepitaxial chemical vapor deposition (CVD) grown semiconducting diamond is used to build an ultra-fast neutron detector. Diamond based neutron detectors are extant technology, but typically limited to neutron energies of less than 14 MeV. This work introduces the Positionally Opposed Schottky Semi-Metal (POSSM) solid state neutron detector. The POSSM device employs two boron-doped P-type semiconducting diamonds in conjunction with a lanthanide foil to create a pair of Schottky junction diodes with a shared cathode. Under reverse bias the diamond-Schottky diodes have undetectable reverse bias leakage current, resulting in a detector with excellent signal-to-noise properties. Preamplifier circuitry has been designed to exploit the favorable properties of the Schottky architecture. Field testing of the device at the Los Alamos Neutron Science Center (LANSCE) yielded successful ultra-fast neutron detection with excellent charge conversion efficiency. Several drawbacks were identified in the performance of the POSSM detector, mainly involving durability of the diodes and speed of the preamplifier. An improved design was developed and is presented in this work, though the improved design has not been built.Secondly, this work presents a novel framework for the simulation of quantum color center formation in diamond. Diamond color centers have been shown to have unique quantum spin properties making them of interest to quantum computing and field sensing. A mesoscale reaction-diffusion framework is developed and a computational solver is built. The Color Center ANnealing And Reaction-Diffusion (CCANARD) program solves the nonlinear reaction-diffusion system by linearization using the Gateaux Derivative and the Crank-Nicolson method. CCANARD is benchmarked for computational efficiency and accuracy. The results are presented and analyzed. An experiment is proposed to further test and develop CCANARD.
Book Synopsis Dual-side Etched Microstructured Semiconductor Neutron Detectors by : Ryan G. Fronk
Download or read book Dual-side Etched Microstructured Semiconductor Neutron Detectors written by Ryan G. Fronk and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in high-efficiency replacements for thin-film-coated thermal neutron detectors led to the development of single-sided microstructured semiconductor neutron detectors (MSNDs). MSNDs are designed with micro-sized trench structures that are etched into a vertically-oriented pvn-junction diode, and backfilled with a neutron converting material, such as 6LiF. Neutrons absorbed by the converting material produce a pair of charged-particle reaction products that can be measured by the diode substrate. MSNDs have higher neutron-absorption and reaction-product counting efficiencies than their thin-film-coated counterparts, resulting in up to a 10x increase in intrinsic thermal neutron detection efficiency. The detection efficiency for a single-sided MSND is reduced by neutron streaming paths between the conversion-material filled regions that consequently allow neutrons to pass undetected through the detector. Previously, the highest reported intrinsic thermal neutron detection efficiency for a single MSND was approximately 30%. Methods for double-stacking and aligning MSNDs to reduce neutron streaming produced devices with an intrinsic thermal neutron detection efficiency of 42%. Presented here is a new type of MSND that features a complementary second set of trenches that are etched into the back-side of the detector substrate. These dual-sided microstructured semiconductor neutron detectors (DS-MSNDs) have the ability to absorb and detect neutrons that stream through the front-side, effectively doubling the detection efficiency of a single-sided device. DS-MSND sensors are theoretically capable of achieving greater than 80% intrinsic thermal neutron detection efficiency for a 1-mm thick device. Prototype DS-MSNDs with diffused pvp-junction operated at 0-V applied bias have achieved 53.54±0.61%, exceeding that of the single-sided MSNDs and double-stacked MSNDs to represent a new record for detection efficiency for such solid-state devices.
