A neutron producing target for BINP accelerator-based neutron source

Applied Radiation and Isotopes, 2009
An innovative accelerator-based neutron source for BNCT has just started operation at the Budker Institute of Nuclear Physics, Novosibirsk. One of the main elements of the facility is a lithium target producing neutrons via the threshold (7)Li(p,n)(7)Be reaction at 25 kW proton beam with energies of 1.915 MeV or 2.5 MeV. The design of an optimal target

An accelerator-based cold neutron source

Nuclear Instruments and Methods in Physics Research, 1982
Abstract We have developed and installed an efficient and very simple pulsed cold neutron source in a modest capacity electron linear accelerator. Solid methane at 20 K was adopted as the cold moderator. The device has demonstrated satisfactory performance and reliable operation over extended periods.

An accelerator-based neutron source for fast neutron brachytherapy

AIP Conference Proceedings, 1997
7Li(p,n), 9Be(d,n) reactions can be good neutron sources for interstitial or intracavity treatment of solid tumors. Dosimetry simulations and heat transfer calculations indicate that dose rate must be limited by heat removal from the target. A tube-in-tube prototype has been constructed. The target will be placed at the bottom of the inner tube.

Accelerator-based fast neutron sources for neutron therapy

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006
Abstract The wide usage of neutron therapy in radio oncology could be provided by construction of economical and compact proton and deuteron accelerators with energy of 2–3 MeV, which could be installed at clinic. One goal of this work was to perform new neutron-yield measurements from different targets and derive consistent data on neutron sources ...

Plasma window performance and scaling for an accelerator-based neutron source

Review of Scientific Instruments, 2023
A “plasma window” was developed for use with a SHINE accelerator-based neutron source. In this work, the design of the plasma window is presented along with results demonstrating successful operation in deuterium over a range of aperture diameters (5–12 mm), gas flow rates (3.5 to 12.5 slm), and input powers (10–55 kW).

Accelerator-based source of epithermal neutrons for neutron capture therapy

Atomic Energy, 2004
Computational studies are performed for choosing an optimal material and dimensions of a moderator for forming a beam of epithermal neutrons for boron-neutron-capture therapy based on a proton accelerator and the reaction 7 Li(p, n)7 Be as the neutron source. It is shown that the best material for this is magnesium fluoride. An optimal configuration is

Observation of Neutron Skyshine from an Accelerator Based Neutron Source

AIP Conference Proceedings, 2011
A key feature of neutron based interrogation systems is the need for adequate provision of shielding around the facility. Accelerator facilities adapted for fast neutron generation are not necessarily suitably equipped to ensure complete containment of the vast quantity of neutrons generated, typically >1011 n⋅s−1. Simulating the neutron leakage from a

An accelerator based steady state neutron source

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1986
Abstract Using high current, cw linear accelerator technology, a spallation neutron source can achieve much higher average intensities than existing or proposed pulsed spallation sources. With about 100 mA of 300 MeV protons or deuterons, the accelerator based neutron research facility (ABNR) would initially achieve the 10 16 n/cm 2 s thermal flux ...

Measurement of Parameters of Neutron Radiation on the Accelerator-Based Epithermal Neutron Source

2021
The accelerator-based epithermal neutrons source, proposed and created in the Budker Institute of Nuclear Physics, provides the generation and formation of a neutron flux suitable for testing the boron neutron capture therapy of malignant tumors. The paper presents and discusses the results of studies using activation techniques. Using activation foils

A shielding design for an accelerator-based neutron source for boron neutron capture therapy

Applied Radiation and Isotopes, 2004
Research in boron neutron capture therapy (BNCT) at The Ohio State University Nuclear Engineering Department has been primarily focused on delivering a high quality neutron field for use in BNCT using an accelerator-based neutron source (ABNS). An ABNS for BNCT is composed of a proton accelerator, a high-energy beam transport system, a (7)Li target, a ...
