Epithermal neutron instrumentation at ISIS [PDF]

open access: yesJournal of Physics: Conference Series, 2014
The advent of pulsed neutron sources makes available high epithermal neutron fluxes (in the energy range between 500 meV and 100 eV). New dedicated instrumentation, such as Resonance Detectors, was developed at ISIS spallation neutron source in the last years to apply the specific properties of this kind of neutron beam to the study of condensed matter.

Epithermal neutron beam interference with cardiac pacemakers [PDF]

open access: yesApplied Radiation and Isotopes, 2011
In this paper, a phantom study was performed to evaluate the effect of an epithermal neutron beam irradiation on the cardiac pacemaker function. Severe malfunction occurred in the pacemakers after substantially lower dose from epithermal neutron irradiation than reported in the fast neutron or photon beams at the same dose rate level.

Study of prompt gamma and neutron emission for real-time range verification in proton and carbon-ion therapy. [PDF]

open access: yesMed Phys
Abstract Background Accurate range verification is crucial in hadrontherapy to fully exploit the ballistic advantages of charged particles and prevent damage to healthy tissues. Among the proposed approaches, prompt gamma imaging (PGI) has emerged as an effective technique for real‐time monitoring, but its performance is limited by the intense neutron ...
