Determination of neutron fracture functions from a global QCD analysis of the leading neutron production at HERA
In this article, we present our global QCD analysis of leading neutron production in deep inelastic
scattering at H1 and ZEUS collaborations. The analysis is performed in the framework of a perturbativeQCD description for semi...
طراحی هم خط ساز بهینه برای دستگاه IVNAA
Neutron activation is one of the used methods in treatment and distinguish of diseases in which considering energy and number of emitted gamma, type and amount of trace elements of body are determined. Precision of measurement, uniformity...
A neutron scattering soil moisture measurement system with a linear response
A prototype moisture measurement system was designed and constructed, based on neutron scattering, for
preforming measurements in the laboratory. The system consisted of a rectangular soil container, an 241Am/Be neutron source and two...
A plastic scintillator-based 2D thermal neutron mapping system for use in BNCT studies
In this study, a scintillator-based measurement instrument is proposed which is capable of measuring a two-dimensional map of thermal neutrons within a phantom based on the detection of 2.22MeV gamma rays generated via nth+H→D+γ reaction...
Characterization of a new shielding rubber for use in neutron–gamma mixed fields
A variety of formulations was investigated for the fabrication of an appropriate shielding rubber to be used in neutron–gamma mixed fields. Having considered the required mechanical properties together with tungsten as the gamma-ray absorbing...
Digital neutron-gamma discrimination with scintillators: An innovative approach
In this paper, a digital neutron–gamma discrimination (DNGD) method with an NE213 scintillator has been proposed in which the anode pulse is divided into two different pulses, one representing the amplitude and the other characterizes the DNGD...
Design and Fabrication of a Data Acquisition System for Pulsed Neutron Flux Measurement of Plasma Focus Devices
Silver-activated Geiger counters together with a polyethylene layer as neutron moderator are frequently
used in pulsed neutron flux measurements in research studies with plasma focus (PF) devices. In this
study, an array of seven...
Review on Fast Neutron Therapy
This study reviews neutron applications in therapy. Applications of neutrons have a long history in nuclear medicine and different therapy centers have started fast neutron treatment since 1976. This treatment is now routinely performed...
