Anomalous pinch in electron-electron beam collision
W. Zhang, T. Grismayer, L. O. Silva
We show that an anomalous pinch can occur in ultrarelativistic electron-electron or positron-positron beam interaction, caused by the combined interplay of collective beam motion (…
Laser-Driven, Ion-Scale Magnetospheres in Laboratory Plasmas. I. Experimental Platform and First Results
D. B. Schaeffer, F. D. Cruz, R. S. Dorst +7
Magnetospheres are a ubiquitous feature of magnetized bodies embedded in a plasma flow. While large planetary magnetospheres have been studied for decades by spacecraft, ion-scale…
Simulation and Experimental Study of Proton Bunch Self-Modulation in Plasma with Linear Density Gradients
P. I. Morales Guzmán, P. Muggli, R. Agnello +88
We present numerical simulations and experimental results of the self-modulation of a long proton bunch in a plasma with linear density gradients along the beam path. Simulation re…
Kinetic instability in inductively oscillatory plasma equilibrium
Fábio Cruz, Thomas Grismayer, Luis O. Silva
A uniform in space, oscillatory in time plasma equilibrium sustained by a time-dependent current density is analytically and numerically studied resorting to particle-in-cell simul…
Bandwidth effects in stimulated Brillouin scattering driven by partially incoherent light
B. Brandão, J. E. Santos, R. M. G. M. Trines +2
A generalized Wigner-Moyal statistical theory of radiation is used to obtain a general dispersion relation for Stimulated Brillouin Scattering (SBS) driven by a broadband radiation…
High-order harmonic generation in an electron-positron-ion plasma
W. L. Zhang, T. Grismayer, K. M. Schoeffler +2
The laser interaction with an electron-positron-ion mixed plasma is studied, from the perspective of the associated high-order harmonic generation. For an idealized mixed plasma wh…
