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.

Linac-driven spallation-neutron source [PDF]

Proceedings Particle Accelerator Conference, 2002
Strong interest has arisen in accelerator-driven spallation-neutron sources that surpass existing facilities (such as ISIS at Rutherford or LANSCE at Los Alamos) by more than an order of magnitude in beam power delivered to the spallation target. The approach chosen by Los Alamos (as well as the European Spallation Source) provides the full beam energy

Slight compositional variation-induced structural disorder-to-order transition enables fast Na+ storage in layered transition metal oxides

Nature Communications, 2022
In layered transition metal oxides as cathode active materials for Na-ion batteries, Na+ diffusion kinetics are impacted by Na+/vacancy ordering. Here, the authors suggest that the P2-type Na2/3Ni1/3Mn2/3O2 with large zigzag ordering exhibits high Na ...

Dynamic Covalent Networks of Molecular Clusters for Hard and Impact‐Resistant Glass with Feasible Processability

Advanced Science, EarlyView.
Molecular granular material glass is fabricated by crosslinking sub‐nm POSS clusters with dynamic borate ester bonding while the materials combine high transparency, modulus, and hardness with superior impact resistance and (re)processability, offering a promising strategy for creating robust yet highly processable organic glasses.
