Radiation effects on optical frequency domain reflectometry fiber-based sensor [PDF]

Optics Letters, 2015
We investigate the radiation effects on germanosilicate optical fiber acting as the sensing element of optical frequency domain reflectometry devices. Thanks to a new setup permitting to control temperature during irradiation, we evaluate the changes induced by 10 keV x rays on their Rayleigh response up to 1 MGy in a temperature range from -40°C up to

A Unified Vector Electromagnetic Framework for Ionospheric Scintillation and Polarization Effects in GNSS

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...

Towards machine‐learning‐based on‐the‐fly analysis of neutron reflectometry

Journal of Applied Crystallography, Volume 59, Issue 3, Page 765-773, June 2026.
An automated machine‐learning‐based processing and analysis workflow for neutron reflectometry data is presented. The approach has been successfully used for on‐the‐fly analysis during an experiment at the Institut Laue–Langevin (Grenoble, France) and can be adapted to work at other neutron facilities seeking to enable real‐time feedback‐driven ...
