  1. link.aps.org

    Experiments using an electron beam produced by laser-wakefield acceleration have shown that varying the overall beam-plasma interaction length results in current filamentation at lengths that exceed the laser depletion length in the plasma. Three-dimensional simulations show this to be a combination of hosing, beam erosion, and filamentation of the decelerated beam. This work suggests the ...

    ultra-intense laser pulse as it propagates through a low-density plasma [2]. As the leading edge of the laser ion-izes the gas, the high electric field gradients expel the electrons via the ponderomotive force, leaving behind a bare ion cavity. The resulting electron density profile resembles a near-spherical "bubble" following the laser ...

    However, as the laser pulse propagates it continuously loses energy to the plasma in generating the wakefield. The length over which the laser pulse can sustain a wakefield is given by the pump depletion length, and in the nonlinear 3D regime this is given as Lpd ¼ ðncr =n0 Þc p , where ncr ¼ !20 me 0 =e2 is the critical density for a laser ...

  6. Feb 2, 2024The use of plasma waves powered by intense laser pulses or relativistic charged particle beams is gaining particular attention as a potential next-generation accelerator for various applications in medicine, material sciences, and high-energy physics (1-3).In a laser wakefield accelerator (LWFA) (), the plasma electrons are pushed away from the ion background by the ponderomotive force of ...

    May 7, 2024A particle-beam-generating method—called wakefield acceleration—uses proton bunches, which can fragment into high-density filaments as a result of their interactions with plasma, new experiments show. ...

    In the experiments reported here, the filamentation of ultrashort laser pulses, due to non-optimal choice of focusing geometry and/or electron number density, has a severely deleterious effect on monoenergetic electron beam production in laser wakefield accelerators. ...

    The fundamental idea of Laser Wakefield Acceleration (LWFA) is reviewed. An ultrafast intense laser pulse drives coherent wakefields of relativistic amplitude with the high phase velocity robustly supported by the plasma. The structures of wakes and sheaths in plasma are contrasted. While the large amplitude of wakefields involves collective resonant oscillations of the eigenmode of the entire ...
