Production of epithermal neutron beams for BNCT

AIP Conference Proceedings, 1999
Boron Neutron Capture Therapy, a promising modality for the treatment of malignant tumors, relies on the use of neutron beams of suitable energy and intensity. For deep-seated tumors, simulations indicate that the optimal neutron energy is in the epithermal region, and in particular between 1 and 10 keV.

Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 801-818, May 2026.
Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Effect of Epithermal Fission on Neutron Multiplication [PDF]

Journal of Nuclear Science and Technology, 1966
A formula for the effect of epithermal fission on the neutron multiplication factor is derived with a modified four factor approach. The fraction of neutron multiplication due to epithermal fission is expressed by The deduction factor sensitively depends on neutron leakage in the fast and the resonance regions through the effective number of neutrons ...

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 ...

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.

The JULIC Neutron Platform, a testbed for HBS [PDF]

EPJ Web of Conferences
The JULIC Neutron Platform was set up at the COSY facility in Jülich as a testbed for the HBS project. Its center is a target station prototype using a tantalum target and a 45 MeV proton beam with a maximum beam power of a few watts.

Measurement of Neutron Parameters in the Treatment Beamof In-Hospital Neutron Irradiator

Journal of Isotopes
In order to verify the design specifications of in-hospital neutron irradiator (IHNI), the neutron fluence rates at the exit of its thermal and epithermal neutron beams were measured by using the method of cadmium difference.
