Proton Acceleration in a Laser-induced Relativistic Electron Vortex
Longqing Yi, István Pusztai, Alexander Pukhov +2
We show that when a solid plasma foil with a density gradient on the front surface is irradiated by an intense laser pulse at a grazing angle, around 80 degrees, a relativistic ele…
Dynamics of positrons during relativistic electron runaway
Ola Embréus, Linnea Hesslow, Mathias Hoppe +3
Sufficiently strong electric fields in plasmas can accelerate charged particles to relativistic energies. In this paper we describe the dynamics of positrons accelerated in such el…
Electron beam driven generation of frequency-tunable isolated relativistic sub-cycle pulses
Illia Thiele, Evangelos Siminos, Tünde Fülöp
We propose a novel scheme for frequency-tunable sub-cycle electromagnetic pulse generation. To this end a pump electron beam is injected into an electromagnetic seed pulse as the l…
Proton acceleration by a pair of successive ultraintense femtosecond laser pulses
Julien Ferri, Lovisa Senje, Malay Dalui +12
We investigate the target normal sheath acceleration of protons in thin aluminum targets irradiated at relativistic intensity by two time-separated ultrashort (35 fs) laser pulses.…
Effect of partially ionized impurities and radiation on the effective critical electric field for runaway generation
Linnea Hesslow, Ola Embréus, George J Wilkie +2
We derive a formula for the effective critical electric field for runaway generation and decay that accounts for the presence of partially ionized impurities in combination with sy…
