Test of Fibre Bragg Gratings samples under High Fast Neutrons Fluence [PDF]

EPJ Web of Conferences, 2018
Optical fibre sensors (OFS) are worthy of interest for measurements in nuclear reactor thanks to their unique features, particularly compact size and remote multi-point sensing for some of them.

Transmutation detectors for fast neutron fluence measurements [PDF]

EPJ Web of Conferences
Transmutation detectors (TMDs) are based on a similar principle as neutron activation detectors (NADs). In both cases, the neutron fluence is estimated from the number of reactions in the detectors.

Fast Neutron Fluence Rate Measurement for the Neutron Beams at IHNI-1

Journal of Isotopes, 2017
To validate and determine the contamination source term of fast neutrons produced by the first in-Hospital Neutron Irradiator (IHNI-1) for boron neutron capture therapy (BNCT), a boron-covered 235U fission chamber was designed to be used for the ...

Study of prompt gamma and neutron emission for real-time range verification in proton and carbon-ion therapy. [PDF]

Med Phys
Abstract Background Accurate range verification is crucial in hadrontherapy to fully exploit the ballistic advantages of charged particles and prevent damage to healthy tissues. Among the proposed approaches, prompt gamma imaging (PGI) has emerged as an effective technique for real‐time monitoring, but its performance is limited by the intense neutron ...

A Method to Estimate the Fast-Neutron Fluence for the Hiroshima Atomic Bomb [PDF]

Journal of the Physical Society of Japan, 1994
A new method to estimate the fast-neutron fluence of the Hiroshima atomic bomb is proposed. 63 Ni produced by the 63 Cu(n, p) 63 Ni reaction provides a unique measure by which to estimate the fast-neutron fluence of the Hiroshima/Nagasaki atomic bombs, because the half-life of 63 Ni is 100 years and 70% of the 63 Ni produced in a copper piece presently

Calculation and analysis of fast neutron fluence of pressure vessel in AP1000 reactor [PDF]

EPJ Web of Conferences
The structural integrity of the reactor pressure vessel plays an important role in the safe operation of AP1000 nuclear power plant. Radiation damage of fast neutrons is the main factor leading to pressure vessel material deterioration.

Epithermal neutron activation dosimetry–(n, γ) reactions under boron-based filters [PDF]

Scientific Reports
Neutron activation dosimetry is the primary method for the determination of the neutron flux or fluence, and in general, it is sensitive to the thermal and resonance energy ranges (radiative capture reactions– $$(n,\gamma )$$ ( n , γ ) reactions) and the

Influence of Surface Isolation Layers on High-Voltage Tolerance of Small-Pitch 3D Pixel Sensors [PDF]

Sensors
In recent years, 3D pixel sensors have been a topic of increasing interest within the High Energy Physics community. Due to their inherent radiation hardness, demonstrated up to a fluence of 3×1016 1 MeV equivalent neutrons per square centimeter, 3D ...

Modelling of a SiC Based Detector for the Interpretation of 14.1 MeV Neutrons Measurements [PDF]

EPJ Web of Conferences, 2023
Wide-bandgap semiconductor-based fast neutron detectors such as silicon carbide (SiC) seem to be a promising concept to meet the implementation requirements as well as the performance specifications for fusion and fission environments such as radiation ...

Electrical characteristics and deep-level transient spectroscopy of a fast-neutron-irradiated 4H–SiC Schottky barrier diode

Nuclear Engineering and Technology, 2023
The dependence of the electrical characteristics on the fast neutron fluence of an epitaxial 4H–SiC Schottky barrier diode (SBD) was investigated. The 30 MeV cyclotron was used for fast neutron irradiation.
