Latitude Survey of Neutrons and Muons to Determine Cosmic Ray Neutron Sensing Yield Functions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic Ray Neutron Sensing (CRNS) is a ground‐based technique that utilizes epithermal neutron measurements as a proxy for environmental hydrogen content. Similarly to other ground‐based cosmic ray detectors (e.g., neutron monitors), CRNS detectors are affected by the solar cycle and space weather events.

Improving polarized neutron reflectometry experiments on soft‐matter samples: optimization of the solid substrate structure

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1192-1199, August 2026.
We demonstrate a Fisher‐information‐based strategy for optimizing the solid substrate structure in polarized neutron reflectometry experiments on soft‐matter samples. The approach identifies magnetic reference layer designs that improve experimentally accessible information and provides a general framework for more efficient reflectometry experiment ...

Grazing‐incidence scattering surveyed: towards reference methods for alignment and calibration

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1247-1253, August 2026.
With the recent gain in popularity of grazing‐incidence instruments, harmonization is needed to establish intercomparability. This review of existing instruments and methods highlights the diversity of approaches in the community and is a first step towards reference methods.Grazing‐incidence small‐angle scattering (GISAS) is a relatively young ...

Integrated analysis with iCM‐SANS, SAXS and MD simulations for dynamics of multi‐domain proteins

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1270-1281, August 2026.
Segmental deuteration, combined with inverse contrast‐matching small‐angle neutron scattering (iCM‐SANS) and small‐angle X‐ray scattering (SAXS), provides structural constraints that improve discrimination of conformation ensembles of multi‐domain proteins derived from molecular dynamics (MD) simulations.Multi‐domain proteins (MDPs) adopt diverse ...

A neutron microscope using a nested Wolter‐I condenser and a bank of diffractive–refractive achromatic objectives

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1282-1293, August 2026.
A neutron microscope is presented comprising a Wolter‐I nested mirror optic as condenser and a 2D array of neutron achromats as objective.We present a nested Wolter‐I mirror design for a neutron condenser, which is based on established X‐ray telescope technology.

Dose‐dependent structural and electron‐density features in the lytic polysaccharide monooxygenase NcAA9D

Acta Crystallographica Section D, Volume 82, Issue 8, Page 900-914, August 2026.
A series of 36 structures of the Neurospora crassa LPMO NcAA9D were refined against X‐ray crystal datasets collected with increasing dose from a single crystal to provide insights into dose‐dependent structural changes at the active site of the enzyme.

Measurements of proton beam flux and energy of APEP using foil activation technique

Nuclear Engineering and Technology
The activation method of metallic foils is an important technique to measure the flux and energy of proton beams. In this paper, the method was used to measure the CSNS APEP proton flux at seven nominal proton energies ranging from 10 MeV to 70 MeV for ...
