    With the availability of intense pulse lasers, it is now possible to construct accelerators in plasmas, that harness the energy of the laser and transfer it to energetic particles. Here we consider direct laser acceleration in plasma channels, analytically and with particle-in-cell simulations. Our study of electron acceleration provides compact scaling laws applicable to the regime of extreme ...

    The direct laser acceleration (DLA) of electrons in underdense plasmas can provide hundreds of nC of electrons accelerated to near-GeV energies using currently available lasers. Here we demonstrate the key role of electron transverse displacement in the acceleration and use it to analytically predict the expected maximum electron energies. The energy scaling is shown to be in agreement with ...

    We propose to extend the acceleration distance of the pairs using a plasma channel, where the laser can be self-guided and the pairs can experience Direct Laser Acceleration (DLA) [46-54]. We demonstrate that for intense lasers propagating in a plasma channel, a dense central electron beam (∼800 nC) is self-injected and copropagates with the

    During the propagation through 1.8 mm of plasma, the laser has lost less than 25% of its total energy and therefore the acceleration could potentially continue further within a longer plasma channel. Using a channel with a smaller transverse size would be favourable to maintain a high laser intensity over a longer propagation distance.

    We use analytical methods and particle-in-cell simulation to investigate the origin of electrons accelerated by the process of direct laser acceleration driven by high-power laser pulses in preformed narrow cylindrical plasma channels. The simulation shows that the majority of accelerated electrons are originally located along the interface between the channel wall and the channel interior ...
  9. Intense lasers enable generating high- energy particle beams in university- scale laboratories. With the direct laser acceleration (DLA) method, the leading part of the laser pulse ionizes the target material and forms a positively charged ion plasma channel into which electrons are injected and accelerated. The high energy conversion effi-
