Operational results with fast automatic beam-based LHC collimator alignment [PDF]

open access: yes, 2013
The CERN Large Hadron Collider (LHC) is the largest and highest-energy particle accelerator ever built. It is designed to collide particles at a centre-of-mass energy of 14 TeV to explore the fundamental forces and constituents of matter.

Beam-domain hybrid time-switching and power-splitting SWIPT in full-duplex massive MIMO system

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
In this paper, we consider the beam-domain hybrid time-switching (TS) and power-splitting (PS) simultaneous wireless information and power transfer (SWIPT) protocol design in full-duplex (FD) massive multiple-input multiple-output (MIMO) system, where ...

Proton beam therapy should remain in the public domain [PDF]

open access: yesCanadian Medical Association Journal, 2019
We would like to respond to the article “Proton beam therapy for cancer” by Tsang and Patel that was published recently in CMAJ .[1][1] As the authors state, radiotherapy is a critical element of treatment for one-third to half of all patients with cancer.

Equilibrium of longitudinal bunch distributions in electron storage rings with arbitrary impedance sources and generic filling patterns

open access: yesPhysical Review Accelerators and Beams, 2023
A new self-consistent semianalytical method for calculating the stationary beam-induced voltage in the presence of arbitrary filling patterns and impedance sources in electron storage rings is presented.

Electron-beam-induced ferroelectric domain behavior in the transmission electron microscope: Toward deterministic domain patterning [PDF]

open access: yes, 2016
We report on transmission electron microscope beam-induced ferroelectric domain nucleation and motion. While previous observations of this phenomenon have been reported, a consistent theory explaining induced domain response is lacking, and little ...

Analysis of the vibration characteristics of tail beam of the hydraulic support under random coal gangue particle slip conditions

open access: yesPLoS ONE, 2022
To study the influence of the gangue content of coal gangue particles on the vibration signal of the tail beam under sliding condition, this paper combines three-dimensional(3D) laser scanning technology with the finite element method, establishes a ...

saturated poroelastic halfspace, beam, bending consolidation, time-domain

open access: yesYantu gongcheng xuebao, 2017
The coal permeability is the key parameter for the gas seepage characteristics and the migration law, and the structural anisotropy of the coal seam makes the permeability have obvious orientation dependence.

Elastic immersive wave experimentation: Theory and physical implementation

open access: yesPhysical Review Research, 2019
We present a proof of concept of elastic immersive wave experimentation. A physical experiment of finite volume is connected with a numerical domain via the novel theory of immersive boundary conditions.
