neutronprobe

Neutronprobe is a conceptual instrument in the field of neutron science designed to detect and characterize neutron fields in materials and environments. It is envisaged as a portable or laboratory-scale device capable of mapping neutron flux, energy spectra, and source localization with varying degrees of spatial resolution.

Operating in active or passive modes, a neutronprobe may employ a pulsed or continuous neutron source to illuminate a sample, paired with an array of detectors such as helium-3 proportional counters, boron-10 glass, lithium-loaded scintillators, or solid-state detectors. Time-of-flight measurements or energy-dispersive techniques enable estimation of neutron energies, while shielding and collimation reduce background. In passive mode, the instrument records ambient or spontaneous neutron emissions to infer material properties.

Potential applications include nuclear safeguards and nonproliferation verification, materials characterization, industrial imaging, geological and oil- and gas-well logging, and planetary science where neutron signatures reveal composition and water content.

Design considerations emphasize detection efficiency, energy resolution, portability, and robust data processing. Calibration relies on known neutron sources and reference materials, with data analysis integrating spectra, spatial mappings, and simulation tools to interpret results. The instrument may be deployed in laboratories, field sites, or remote environments, depending on source type and safety requirements.

Challenges for a neutronprobe include background neutrons, radiation safety concerns, detector aging, cost, and the need for shielding. Regulatory and safety frameworks depend on the chosen neutron source and the application domain.
