The epithermal neutron irradiation station for boron neutron capture therapy (BNCT) at the FiR 1 in Otaniemi

, 1996
The optimal neutron field for BNCT would have only neutrons of the epithermal energy range and would be free of γ-radiation. Such a field penetrates several centimeters into the tissue but does not cause damage so much as higher energy neutrons would. In

The epithermal neutron beam for BNCT under construction at TAPIRO: Physics

, 2006
A column to provide an epithermal neutron beam suitable for experimental and clinical BNCT is nearing completion at the TAPIRO reactor (ENEA Casaccia, Rome). TAPIRO is a compact, low power (5 kW), helium-cooled, fast reactor.

The influence of an additional filter in epithermal neutron activation analysis

, 1989
Additional filters of tungsten and sodium in different thicknesses have been used in the epithermal neutron activation analysis of geological samples to reduce the interferences caused by resonance neutron capture in these two elements.

Dose measurements and calculations in the epithermal neutron beam at the Brookhaven Medical Research Reactor (BMRR) [PDF]

, 1990
The characteristics of the epithermal neutron beam at BMRR were measured, calculated, and reported. This beam has already been used for animal irradiations. We anticipate that it will be used for clinical trials.

Coarse-Scaling Adjustment of Fine-group Neutron Spectra for Epithermal Neutron Beams in BNCT using Multiple Activation Detectors

, 2009
In order to provide an improved and reliable neutron source description for treatment planning in boron neutron capture therapy (BNCT), a spectrum adjustment procedure named coarse-scaling adjustment has been developed and applied to the neutron spectrum

Demonstration of Near-Epithermal Neutron Reflective Optics

Specular reflection of neutrons on material surfaces has been demonstrated in the energy range of 0.09-0.7 eV. The results suggest that the applicable energy range of reflective neutron optics can be extended to the near-epithermal region by using ...

A Technique for Reducing Interferences in Epithermal Neutron Activation Analysis

, 1985
A new epithermal neutron activation technique is described. The technetium is based on the existence of non-overlapping resonance peaks in the neutron absorption cross-section spectra for the nuclides present in the sample to be analyzed.
