High quality GeV proton beams from a density-modulated foil target
T. P. Yu, M. Chen, A. Pukhov
We study proton acceleration from a foil target with a transversely varying density using multi-dimensional Particle-in-Cell (PIC) simulations. In order to reduce electron heating…
Stable laser-driven proton beam acceleration from a two-specie ultra-thin foil
T. P. Yu, A. Pukhov, G. Shvets +1
By using multi-dimensional particle-in-cell simulation, we present a new regime of stable proton beam acceleration which takes place when a two-specie shaped foil is illuminated by…
Simulations of stable compact proton beam acceleration from a two-ion-species ultrathin foil
T. P. Yu, A. Pukhov, G. Shvets +4
We report stable laser-driven proton beam acceleration from ultrathin foils consisting of two ion species: heavier carbon ions and lighter protons. Multi-dimensional particle-in-ce…
Advances in laser-assisted nuclear decay and nuclear excitation
Q. Xiao, J. H. Cheng, Y. Y. Xu +4
From the synthesis and evolution of the elements to the celestial nuclear processes of stellar explosions and neutron star mergers, nuclear physics is the foundation of our underst…
Enhanced collimated GeV monoenergetic ion acceleration from a shaped foil target irradiated by a circularly polarized laser pulse
M. Chen, A. Pukhov, T. P. Yu +1
Using multi-dimensional particle-in-cell (PIC) simulations we study ion acceleration from a foil irradiated by a circularly polarized laser pulse at 1022W/cm^2 intensity. When the…
Predominant Nuclear Excitation by Electron Capture Driven by Beam-Induced Return Currents
Y. Y. Xu, J. T. Qi, H. Peng +5
Predicted nearly five decades ago, nuclear excitation by electron capture (NEEC) remains experimentally elusive because its weak resonant signal is obscured by competing electron-d…
