Book Synopsis Advanced Microstructured Semiconductor Neutron Detectors by : Steven Lawrence Bellinger

Available in PDF, EPUB and Kindle. Book excerpt: The microstructured semiconductor neutron detector (MSND) was investigated and previous designs were improved and optimized. In the present work, fabrication techniques have been refined and improved to produce three-dimensional microstructured semiconductor neutron detectors with reduced leakage current, reduced capacitance, highly anisotropic deep etched trenches, and increased signal-to-noise ratios. As a result of these improvements, new MSND detection systems function with better gamma-ray discrimination and are easier to fabricate than previous designs. In addition to the microstructured diode fabrication improvement, a superior batch processing backfill-method for 6LiF neutron reactive material, resulting in a nearly-solid backfill, was developed. This method incorporates a LiF nano-sizing process and a centrifugal batch process for backfilling the nanoparticle LiF material. To better transition the MSND detector to commercialization, the fabrication process was studied and enhanced to better facilitate low cost and batch process MSND production. The research and development of the MSND technology described in this work includes fabrication of variant microstructured diode designs, which have been simulated through MSND physics models to predict performance and neutron detection efficiency, and testing the operational performance of these designs in regards to neutron detection efficiency, gamma-ray rejection, and silicon fabrication methodology. The highest thermal-neutron detection efficiency reported to date for a solid-state semiconductor detector is presented in this work. MSNDs show excellent neutron to gamma-ray (n/[gamma]) rejection ratios, which are on the order of 106, without significant loss in thermal-neutron detection efficiency. Individually, the MSND is intrinsically highly sensitive to thermal neutrons, but not extrinsically sensitive because of their small size. To improve upon this, individual MSNDs were tiled together into a 6x6-element array on a single silicon chip. Individual elements of the array were tested for thermal-neutron detection efficiency and for the n/[gamma] reject ratio. Overall, because of the inadequacies and costs of other neutron detection systems, the MSND is the premier technology for many neutron detection applications.

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.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods for manufacturing solid-state thermal neutron detectors with simultaneous high thermal neutron detection efficiency (>50%) and neutron to gamma discrimination (>10.sup. 4) are provided. A structure is provided that includes a p+ region on a first side of an intrinsic region and an n+ region on a second side of the intrinsic region. The thickness of the intrinsic region is minimized to achieve a desired gamma discrimination factor of at least 1.0E+04. Material is removed from one of the p+ region or the n+ region and into the intrinsic layer to produce pillars with open space between each pillar. The open space is filed with a neutron sensitive material. An electrode is placed in contact with the pillars and another electrode is placed in contact with the side that is opposite of the intrinsic layer with respect to the first electrode.
