Buoy‐Based Detection of Low‐Energy Cosmic‐Ray Neutrons to Monitor the Influence of Atmospheric, Geomagnetic, and Heliospheric Effects

Earth and Space Science
Cosmic radiation on Earth responds to heliospheric, geomagnetic, atmospheric, and lithospheric changes. In order to use its signal for soil hydrological monitoring, the signal of thermal and epithermal neutron detectors needs to be corrected for external

Use of 3He Neutron Sensors for Planetary Penetrator Experiments

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract This paper provides a report on a test that was carried out over 20 years ago to demonstrate that two 3He gas proportional neutron sensors could survive a high‐impact penetrator test. This test was carried out as part of a risk reduction effort for a proposed mission that would send multiple penetrators to landing locations within lunar ...

Predicting a Gapless Spin-1 Neutral Collective Mode branch for Graphite

, 2001
Using the standard tight binding model of 2d graphite with short range electron repulsion, we find a gapless spin-1, neutral collective mode branch {\em below the particle-hole continuum} with energy vanishing linearly with momenta at the $\Gamma$ and $K$

Soil Moisture Time Series Using Gamma‐Ray Spectrometry Detection Representing a Scale of Tens‐of‐Meters

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Recently, stationary gamma‐ray spectrometry (GRS) detection was introduced in the field of hydrology for continuous soil moisture estimation at a unique spatial scale of tens‐of‐meters. This method offers promise for applications such as early warning systems for emerging droughts and floods, ecosystem health evaluation, and optimizing ...

Development of a Time-Gated Epithermal Neutron Spectrometer for Resonance Absorption Measurements Driven by a High-Intensity Laser

Quantum Beam Science
The advance of laser-driven neutron sources (LDNSs) has enabled neutron resonance spectroscopy to be performed with a single shot of a laser. In this study, we describe a detection system of epithermal (∼eV) neutrons especially designed for neutron ...

A Study of the Production of Neutrons for Boron Neutron Capture Therapy using a Proton Accelerator [PDF]

, 2014
Boron Neutron Capture Therapy (BNCT) is a binary cancer therapy particularly well-suited to treating aggressive tumours that exhibit a high degree of infiltration of the surrounding healthy tissue. Such tumours, for example of the brain and lung, provide

Muon Catalyzed Fusion in 3 K Solid Deuterium

, 1997
Muon catalyzed fusion in deuterium has traditionally been studied in gaseous and liquid targets. The TRIUMF solid-hydrogen-layer target system has been used to study the fusion reaction rates in the solid phase of D_2 at a target temperature of 3 K ...

Combined Gamma Ray/neutron Spectroscopy for Mapping Lunar Resources [PDF]

Some elements in the Moon can be resources, such as hydrogen and oxygen. Other elements, like Ti or the minerals in which they occur, such as ilmenite, could be used in processing lunar materials.

A Microscopic T-Violating Optical Potential: Implications for Neutron-Transmission Experiments

, 1994
We derive a T-violating P-conserving optical potential for neutron-nucleus scattering, starting from a uniquely determined two-body $\rho$-exchange interaction with the same symmetry.

Nuclear Data Uncertainty Quantification for Reactor Physics Parameters in Fluorine-19-based Molten Salt Reactors [PDF]

EPJ Web of Conferences
The use of the F-19 isotope in the nuclear fuel cycle is already well established for fuel enrichment, but future plans for Gen-IV reactors, such as Molten Salt Reactors, could utilize a fluorine-based salt as a basis for the fuel.
