Book excerpt: Radiation portal monitors used for interdiction of illicit materials at borders include highly sensitive neutron detection systems. The main reason for having neutron detection capability is to detect fission neutrons from plutonium. The currently deployed radiation portal monitors (RPMs) from Ludlum and Science Applications International Corporation (SAIC) use neutron detectors based upon 3He-filled gas proportional counters, which are the most common large neutron detector. There is a declining supply of 3He in the world, and thus, methods to reduce the use of this gas in RPMs with minimal changes to the current system designs and sensitivity to cargo-borne neutrons are being investigated. Four technologies have been identified as being currently commercially available, potential alternative neutron detectors to replace the use of 3He in RPMs. Reported here are the results of tests of a newly designed boron-lined proportional counter option. This testing measured the neutron detection efficiency and gamma ray rejection capabilities of a system manufactured by Reuter Stokes.

Book Synopsis Neutron Detectors for Scattering Applications by : Yacouba Diawara
Download or read book Neutron Detectors for Scattering Applications written by Yacouba Diawara and published by Springer Nature. This book was released on 2023-08-04 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the most common neutron detectors used in neutron scattering facilities and all of those in use at Oak Ridge National Lab. It starts describing the facilities, instruments and the critical detector parameters needed by various instruments. Then the key components of the 3He-based linear position-sensitive detectors as well as on their electronics, which require particular attention to signal processing and noise reduction, are introduced. One chapter is dedicated to the 3He alternatives where scintillators play a critical role. It also covers emerging neutron detection technologies including semiconductors, vacuum-based devices and their associated readouts, which will be required in the future for high rate and high-resolution neutron detectors. The authors explain the logic behind the choice of materials as well as the various constraints that neutron detectors must respect to be useful. Some of these constraints, such as efficiency and gamma-ray sensitivity are common to all neutron counters while others, like timing resolution, dynamic range, and peak counting rate, depend on the applications. The book guides experts, the nuclear science community, and young scholars through the physical processes and the required electronics in a way that is accessible for those not professionally involved in designing detector’s components and electronic circuits.

Book Synopsis From Parity Violation to Hadronic Structure and more by : Serge Kox
Download or read book From Parity Violation to Hadronic Structure and more written by Serge Kox and published by Springer Science & Business Media. This book was released on 2007-06-07 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost 50 years after the proposal of Lee and Young in 1956 to test the hypothesis of parity violation in weak interactions and the subsequent experimental verification of parity violation by C. S. Wu, parity violation has today become a useful property of weak interactions. This is due to the fact that the focus nowadays has changed: parity violation in weak interactions is no more a topic of investigation but is used as a tool in many different fields ranging from nuclear physics to the search for the hidden extra dimensions requested by string theory. For our first workshop which took place June 5-8, 2002, at the Institut fiir Ke- physik of the Johannes Gutenberg-Universitat Mainz, we concentrated on the in vestigation of the strangeness contribution in the nucleon. This book contains the refereed and selected papers of the second workshop "From Parity Violation to Hadron Structure and more (Part II)", which took place June 8-11, in the Labo- toire de Physique Subatomique et de Cosmologie, in Grenoble. These papers appear in EPJAdirect, the electronic-only part of EPJA, and they are accessible without restrictions. They will also appear in printed form and can be ordered through Springer. The excellent presentations show the dramatic and steady progress in the accuracy of measured parity violating asymmetries over the last few years.

Book Synopsis Design of a 4 Π Neutron Detector for ß-delay Neutron Detection Experiments by : Vitaly Gorlychev
Download or read book Design of a 4 Π Neutron Detector for ß-delay Neutron Detection Experiments written by Vitaly Gorlychev and published by . This book was released on 2014 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beta delayed neutron emission probability is one of the main properties of neutron rich nuclei away from the valley of beta stability. The knowledge of this parameter provides the opportunity to extend the information on: the structure of atomic nuclei and its dependence with the N/Z ratio; the rapid neutron capture nucleosynthesis process (r-process), and hence study the formation of nuclei in supernova explosions; new data for reactor technology applications, since is one of the key features for the safe operation of actual nuclear power plants. The objective of the thesis was to design and test a prototype of a 4p neutron detector for DESPEC experiments related with the measurement of beta delayed neutron emission probabilities. As the neutron emission probabilities are low and the neutron energies are not well known, it is necessary to design a detector with high neutron detection efficiency, and a low dependence with neutron energy for a wide neutron energy ranges. The prototype designed has a mean neutron detection efficiency of the order of 27.1 % and is flat for neutron energies ranging from thermal values to 6 MeV. The detector designed is composed by 20 3He proportional counters at 20 atm, inserted in a polyethylene matrix. The counters are distributed in 2 concentric rings, surrounding a beam hole located at the central axis of the matrix This Master Thesis is divided in three main steps: 1) the analysis of different detector configurations and properties; 2) the selection of the definitive configuration of detector prototype, including the electronics and data acquisition system (DAQ); 3) the test of prototype and calibration with neutron sources. The detector configuration analysis has been done by means of Monte Carlo simulations with the code MCNPX. These MC simulations were useful to find: the optimal pressure of 3He counters; the best number of counters, taking in account the cost and the maximum neutron detection efficiency achievable; the number of counters in each concentric ring, and the distance of rings to the center of polyethylene matrix; the optimal counter length; or the shielding thickness for background radiation reduction. All of these studies were basic to obtain the optimal neutron detector configuration. The design of the detector also involved the selection of the most suitable electronics and Data Acquisition System (DAQ), as is described in this Thesis. This activity was done with the collaboration of the "Instituto de Física Corpuscular (IFIC- Valencia)". This PhD. Thesis includes the description of different tests done to check MC simulations of the neutron detector and the DAQ system. The definitive experiment done to check the detector design was done at IGISOL facility (Jyväskylä University, Finland). This experiment allowed to obtain the detector efficiency, measuring the beta-delayed neutron emission of two well known nuclei: 95Rb and 88Br. The results showed a good agreement between experiment and simulations.
