Heliospheric Transport of Neutron-Decay Protons [PDF]

, 2012
We report on new simulations of the transport of energetic protons originating from the decay of energetic neutrons produced in solar flares. Because the neutrons are fast-moving but insensitive to the solar wind magnetic field, the decay protons are ...

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.

Neutron spectroscopy with the Spherical Proportional Counter

, 2017
A novel large volume spherical proportional counter, recently developed, is used for neutron measurements. Gas mixtures of $N_{2}$ with $C_{2}H_{6}$ and pure $N_{2}$ are studied for thermal and fast neutron detection, providing a new way for the neutron ...

Silicon strip detector with a polyethylene converter as a position sensitive detector for a narrow beam of fast neutrons [PDF]

Ядерна фізика та енергетика, 2009
The possibility of using the silicon strip-detector coated with a polyethylene film for the coordinate determination of fast neutrons has been discussed.

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories

Advanced Engineering Materials, EarlyView.
Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...

Analysis of Radiation Methods for Explosive Materials Detection

East European Journal of Physics
The paper examines the physical aspects of some landmine detection methods based on fast neutron backscattering. An analysis of the reaction products of the interaction of fast, slow, and thermal neutrons with H, C, N, O nuclei, which are part of ...

Exotic beams produced by fast neutrons

Physical Review Special Topics. Accelerators and Beams, 1998
First results from the research and development program PARRNE (Production d'Atomes Radioactifs Riches en NEutrons) are presented. Its aim is the investigation of the optimum conditions for the production of neutron-rich fission fragment beams extracted ...

Analyses of silicon dioxide, magnesium oxide, lead fluoride, bismuth as low-pass velocity filters for neutrons [PDF]

, 1969
Transmission measurement of neutrons by filter materials for low energy neutrons is important for the study of structure and dynamics of condensed matter. Since only thermal neutrons are useful for such experiments, filter materials that transmit thermal

Phenomenological and Physically Based Modeling of Flow Stress and Strengthening Mechanism of Inconel 718

Advanced Engineering Materials, EarlyView.
Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.

Paving the Road for Modern Particle Therapy – What can we Learn from the experience gained with Fast Neutron Therapy in Munich?

Frontiers in Oncology, 2015
While neutron therapy was a highly topical subject in the 70’s and 80’s, today there are only a few remaining facilities offering fast neutron therapy. Nevertheless, up to today more than 30,000 patients were treated with neutron therapy.
