How Proton Incorporation Reshapes Lattice Dynamics In BaSnO3‐Type Proton Conductors

Advanced Science, EarlyView.
Yttrium‐doped BaSnO3 exhibits isotope‐dependent changes in its low‐energy vibrational density of states upon hydration. Comparison of dry, H2O‐, and D2O‐treated samples re‐veals mass‐dependent phonon renormalization linked to proton dynamics near oxygen va‐cancies, providing experimental insight into hydrogen‐coupled lattice excitations in proton ...

Benchmarking Geant4 for spallation neutron source calculations

, 2016
Geant4 is becoming increasingly used for radiation transport simulations of spallation neutron sources and related components. Historically, the code has seen little usage in this field and it is of general interest to investigate the suitability of ...

Quantification and evaluation of strain reduction from small-bubble gas injection in Spallation Neutron Source target vessels

Materials & Design
Small-bubble gas injection has been routinely utilized in the operation of Spallation Neutron Source (SNS) mercury targets since 2017 to mitigate cavitation-induced erosion damage to target vessels. Strain measurements of target vessels collected in-situ

Ion source requirements for pulsed spallation neutron sources [PDF]

AIP Conference Proceedings, 1996
The neutron scattering community has endorsed the need for a high‐power (1 to 5 MW) accelerator‐driven source of neutrons for materials research. Properly configured, the accelerator could produce very short (sub‐microsecond) bursts of cold neutrons, said time structure offering advantages over the continuous flux from a reactor for a large class of ...

A high-resolution neutron diffraction and electron diffraction study of the structure and phase transitions in AgTaO3

APL Materials
The high temperature phase transition behavior of the quantum paraelectric material, AgTaO3, has previously been debated in the literature. To elucidate the phase transitions of AgTaO3, we used neutron powder diffraction and established the phase ...
