A stochastic-hydrodynamic model of halo formation in charged particle beams [PDF]

open access: yes, 2003
The formation of the beam halo in charged particle accelerators is studied in the framework of a stochastic-hydrodynamic model for the collective motion of the particle beam.

Möbius edge band and Weyl-like semimetal flat-band in topological photonic waveguide array by synthetic gauge flux

open access: yesNanophotonics, 2023
The presence of π gauge flux enabled by positive and negative hopping amplitude can lead to Möbius bands, which was recently demonstrated in both realistic acoustic and photonic lattices, twisted at k = π.

Development of a Radio-Frequency Quadrupole Accelerator for the HL-2A/2M Tokamak Diagnostic System

open access: yesApplied Sciences, 2022
In order to figure out the migration and deposition of impurities on the first wall of HL-2A/2M tokamak, Peking University and Southwestern Institute of Physics are co-developing a deuteron RFQ as part of the in situ ion-beam diagnostic for the material.

Towards a compact all-optical terahertz-driven electron source

open access: yesFrontiers in Physics, 2023
In this study, we propose a physical design of a compact all-optical terahertz (THz)-driven electron source. The 300-mm accelerator beamline, powered by a Joule-level laser system, can be easily integrated into the tabletop scale.

Nonlinear double-beam system dynamics [PDF]

open access: yesArchives of Civil Engineering, 2021
Double-beam model is considered in many investigations both theoretical and typically engineering ones. One can find different studies concerning analysis of such structures behaviour, especially in the cases where the system is subjected to dynamic ...

Ion beam analysis based on cellular nonlinear networks [PDF]

open access: yes, 2011
The development of a non- destructive measurement method for ion beam parameters has been treated in various projects. Although results are promising, the high complexity of beam dynamics has made it impossible to implement a real time process control up

Reduction of coherent betatron oscillations in a muon g − 2 storage ring experiment using RF fields

open access: yesNew Journal of Physics, 2020
This work demonstrates that two systematic errors, coherent betatron oscillations (CBO) and muon losses, can be reduced through application of radio frequency (RF) electric fields, which ultimately increases the sensitivity of the muon g − 2 experiments.

Rational Design by Structural Biology of Industrializable, Long-Acting Antihyperglycemic GLP-1 Receptor Agonists

open access: yesPharmaceuticals, 2022
Glucagon-like peptide-1 (GLP-1) is easily degraded by dipeptidyl peptidase-4 (DPP-4) in the human body, limiting its therapeutic effect on type II diabetes.
