Book excerpt: Two-dimensional position sensitive detectors are indispensable in neutron diffraction experiments for determination of molecular and crystal structures in biology, solid-state physics and polymer chemistry. Some performance characteristics of these detectors are elementary and obvious, such as the position resolution, number of resolution elements, neutron detection efficiency, counting rate and sensitivity to gamma-ray background. High performance detectors are distinguished by more subtle characteristics such as the stability of the response (efficiency) versus position, stability of the recorded neutron positions, dynamic range, blooming or halo effects. While relatively few of them are needed around the world, these high performance devices are sophisticated and fairly complex; their development requires very specialized efforts. In this context, we describe here a program of detector development, based on 3He filled proportional chambers, which has been underway for some years at Brookhaven. Fundamental approaches and practical considerations are outlined that have resulted in a series of high performance detectors with the best known position resolution, position stability, uniformity of reliability over time of this type.

This book was released on 2004-01-01 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a Ph.D. dissertation. For probing the structure and dynamics of matter at an atomic, molecular and mesoscopic level, elastic and inelastic neutron scattering, diffractometry, reflectometry and a variety of other neutron scattering methods are of utmost importance. For them the availability of highly efficient and fast large-area position-sensitive neutron detectors is a condition of growing importance. In particular, the upcoming third generation of neutron sources, consisting of high-intensity pulsed spallation neutron sources, in conjunction with current progress in neutron optics will increase the peak neutron flux at the spectrometers' samples positions by more than two orders of magnitude. Consequently, much faster detectors than presently available with improved background are required in order to take full advantage of these increased source strengths and us pulse widths. In addition, due to the higher neutron fluxes, longer flight paths and smaller samples can be used and if higher 'matched' spatial detector resolutions are available better lattice resolutions can be attained. The goal of the research described in this dissertation is to develop a thermal neutron detector that meets as many as possible of the requirements being formulated during the ongoing design of the third generation of neutron sources.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: While the neutron scattering community is bombarded with hints of new technologies that may deliver detectors with high-count-rate capability, high efficiency, gamma-ray insensitivity, and high resolution across large areas, only the time-tested, gas-filled [sup 3]He and scintillation detectors are in widespread use. Future spallation sources with higher fluxes simply must exploit some of the advanced detector schemes that are as yet unproved as production systems. Technologies indicating promise as neutron detectors include pixel arrays of amorphous silicon, silicon microstrips, microstrips with gas, and new scintillation materials. This project sought to study the competing neutron detector technologies and determine which or what combination will lead to a production detector system well suited for use at a high-intensity neutron scattering source.

Book excerpt: We have designed a novel neutron detector system using conventional 3He detector tubes and composites of polyethylene, and graphite. At this time the design consists entirely of MCNP simulations of different detector configurations and materials. These detectors are applicable to low-level passive and active neutron assay systems such as the passive add-a-source and the 252Cf shuffler. Monte Carlo simulations of these neutron detector designs achieved efficiencies of over 35% for assay chambers that can accommodate 55-gal. drums. Only slight increases in the number of detector tubes and helium pressure are required. The detectors also have reduced die-away times. Potential applications are coincident and multiplicity neutron counting for waste disposal and safeguards. We will present the general design philosophy, underlying physics, calculation mechanics, and results.
