Numerical optimization of Rhodium Self-Powered Neutron Detector

Annals of Nuclear Energy, 2018
Abstract Self-Powered Neutron Detector (SPND) has been widely used in reactors to monitor neutron flux due to its adaptability for in-core severe environment. As a typical representative, SPND with Rhodium as its emitter has been modeled in the frame of Geant4, which is good at tracing the history of the particles in simulation and very appropriate ...

Analysis of vanadium Self Powered Neutron Detector’s signal

Annals of Nuclear Energy, 2013
Abstract Self Powered Neutron Detectors (SPNDs) have been widely used for monitoring the neutron flux, either in Nuclear Power Plants (NPPs) as well as in irradiation facilities and medical treatments. Nevertheless, the physical meaning of the parameter used to relate the detector signal (an electric current) to the neutron flux, i.e. , the detector

Development and verification of a simulation toolkit for Self-Powered Neutron Detector

Annals of Nuclear Energy, 2021
Abstract A response simulation toolkit ‘SPNDSignal’ based on Geant4 was developed and verified. SPNDSignal adopts Monte-Carlo method to simulate the coupled neutron-gamma-electron transportation in SPND, and the important physical parameters such as neutron sensitivity and current components can be obtained.

A novel solid state self-powered neutron detector

SPIE Proceedings, 2008
Detection of nuclear materials is critical in preventing traffic of illicit nuclear materials. Several methods that are based on detection of spontaneous or induced emission of fission neutron are considered. Efficient fast and thermal neutron detectors are generally required.

Charge Released by Beta-Decaying Self-Powered Neutron Detectors

Nuclear Science and Engineering, 1976
An equation for the total charge available for release from unit length of an emitter undergoing beta-particle decay in a self-powered neutron detector is derived. This derivation is based on a calculational model of the current response of a self-powered neutron detector developed earlier.

Irradiation tests of prototype self-powered gamma and neutron detectors

2011 2nd International Conference on Advancements in Nuclear Instrumentation, Measurement Methods and their Applications, 2011
In the framework of the SCK·CEN-CEA Joint Instrumentation Laboratory, we are developing and optimizing a self-powered detector for selective in-core monitoring of the gamma field. Several prototypes with bismuth emitters were developed and tested in a pure gamma field (the PAGURE gamma irradiation facility at CEA) and in mixed neutron and gamma fields (
