Neutron Detectors for Scattering Applications
Author: Yacouba Diawara
Publisher: Springer Nature
ISBN: 3031365461
Category : Science
Languages : en
Pages : 257
Book Description
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.

High-Pressure Helium-3 Scintillation Position-Sensitive Detector of Thermal Neutrons

Pages : 13
Book Description
The objective of this study is to demonstrate the feasibility of constructing a compact neutron detector that is sensitive to thermal and epithermal neutrons and has high rejection efficiency relative to gamma-ray background. A two-channel high-pressure 3He scintillation detector is considered for the detection of neutrons in coincidence mode. The detector consists of two large avalanche photodiodes viewing a gas volume filled with pressurized 3He. Experiments with the detector demonstrate high efficiency to neutrons and high rejection ability to gamma rays. Position sensitivity of the detector to thermal neutrons is demonstrated and confirmed with computer simulations.

Position-sensitive Detection of Slow Neutrons
Author:
Publisher:
ISBN:
Category :
Languages : en
Pages : 14
Book Description
This paper sets forth the fundamental principles governing the development of position-sensitive detection systems for slow neutrons. Since neutrons are only weakly interacting with most materials, it is not generally practical to detect slow neutrons directly. Therefore all practical slow neutron detection mechanisms depend on the use of nuclear reactions to ''convert'' the neutron to one or more charged particles, followed by the subsequent detection of the charged particles. The different conversion reactions which can be used are discussed, along with the relative merits of each. This is followed with a discussion of the various methods of charged particle detection, how these lend themselves to position-sensitive encoding, and the means of position encoding which can be applied to each case. Detector performance characteristics which may be of importance to the end user are discussed and related to these various detection and position-encoding mechanisms.
