Proton beam defocusing in AWAKE: comparison of simulations and measurements [PDF]

open access: yes, 2020
In 2017, AWAKE demonstrated the seeded self-modulation (SSM) of a 400 GeV proton beam from the Super Proton Synchrotron (SPS) at CERN. The angular distribution of the protons deflected due to SSM is a quantitative measure of the process, which agrees ...

Clustering of ions at atomic dimensions in quantum plasmas

open access: yes, 2013
By means of particle simulations of the equations of motion for ions interacting among themselves under the influence of newly discovered Shukla–Eliasson attractive force (SEAF) in a dense quantum plasma, we demonstrate that the SEAF can bring ions ...

Measurements of beat wave accelerated electrons in a toroidal plasma [PDF]

open access: yes, 1992
Electrons are accelerated by large amplitude electron plasma waves driven by counter-propagating microwaves with a difference frequency approximately equal to the electron plasma frequency. Energetic electrons are observed only when the phase velocity of

A Rubidium Vapor Source for a Plasma Source for AWAKE

open access: yes, 2017
We present the scheme for a rubidium vapor source that is used as a plasma source in the AWAKE plasma wakefield acceleration experiment. The plasma wakefield acceleration process requires a number of stringent parameters for the plasma: electron density ...

Origins of ion energy distribution function (IEDF) in high power impulse magnetron sputtering (HIPIMS) plasma discharge [PDF]

open access: yes, 1982
The ion energy distribution function (IEDF) in high power impulse magnetron sputtering (HIPIMS) discharges was studied by plasma sampling energy-resolved mass spectroscopy.

The Lukewarm Frontier: Some Cosmological Consequences of 'Low Energy' Physics [PDF]

open access: yes, 2010
In this thesis, we present four projects featuring low characteristic energy scales relative to the scales relevant for supersymmetric dark matter production or inflation. We present a telescope search for decaying relic axions in the 3 − 8 eV mass range.

Amplitude enhancement of the self-modulated plasma wakefields

open access: yes, 2018
Seeded Self-modulation (SSM) has been demonstrated to transform a long proton bunch into many equidistant micro-bunches (e.g., the AWAKE case), which then resonantly excite strong wakefields.

Simulation and theory for two-dimensional beam-plasma instability [PDF]

open access: yes, 2018
A comparative study of the dynamics of the electron beam-plasma system in two spatial dimensions is carried out by means of particle-in-cell (PIC) simulation and quasilinear theory.
