Pulsed Cold Neutron Source [PDF]

Journal of Nuclear Science and Technology, 1976
Abstract A solid methane cold neutron source has been installed in a 45 MeV electron linear accelerator pulsed neutron source. A cold neutron gain factor of 40 has been obtained, and the device has shown a record of safe for extended periods. A description is given of the facility and the performance obtained therewith.

The Development and Application of Multi-Cell Elliptical Superconducting Cavity Pre-Tuning Equipment

Applied Sciences
Elliptical superconducting cavities are widely used in particle accelerators because they can provide stronger acceleration fields than regular cavities. Pre-tuning is required to improve their performance, but the process is time-consuming.

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

Advanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...

Timing properties of radioluminescence in nanoparticle ZnS:Ag scintillators

Optical Materials: X, 2023
As neutron scattering facilities improve, new neutron detectors with high rate capabilities that can cope with increasing flux are required. Most scintillation detectors at neutron scattering facilities employ ZnS:Ag mixed with 6LiF.

Ultrashort Pulsed Neutron Source

Physical Review Letters, 2014
We report on a novel compact laser-driven neutron source with an unprecedented short pulse duration (10(18)  n/cm(2)/s), an order of magnitude higher than any existing source. In our experiments, high-energy electron jets are generated from thin (

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

Advanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

Advanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Kitaev interactions through extended superexchange pathways in the $${j}_{{\mathsf{eff}}}=1/2$$ j eff = 1 / 2 Ru3+ honeycomb magnet RuP3SiO11

Nature Communications
Magnetic materials are composed of the simple building blocks of magnetic moments on a crystal lattice that interact via magnetic exchange. Yet from this simplicity emerges a remarkable diversity of magnetic states.
