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…
Signatures of quantum effects on radiation reaction in laser -- electron-beam collisions
C. P. Ridgers, T. G. Blackburn, D. Del Sorbo +7
Two signatures of quantum effects on radiation reaction in the collision of a ~GeV electron-beam with a high-intensity (>3x10^20W/cm^2) laser-pulse have been considered. We show th…
Symmetry breaking in MAST plasma turbulence due to toroidal flow shear
M. F. J. Fox, F. van Wyk, A. R. Field +3
The flow shear associated with the differential toroidal rotation of tokamak plasmas breaks an underlying symmetry of the turbulent fluctuations imposed by the up-down symmetry of…
Transition to subcritical turbulence in a tokamak plasma
F. van Wyk, E. G. Highcock, A. A. Schekochihin +3
Tokamak turbulence, driven by the ion-temperature gradient and occurring in the presence of flow shear, is investigated by means of local, ion-scale, electrostatic gyrokinetic simu…
Transient electric fields in laser plasmas observed by proton streak deflectometry
T. Sokollik, M. Schnuerer, S. Ter-Avetisyan +9
A novel proton imaging technique was applied which allows a continuous temporal record of electric fields within a time window of several nanoseconds. This "proton streak deflectom…
