While large efforts have been devoted to improving the quality of electron beams from laser plasma accelerators, often to the detriment of the charge, many applications do not require very Database derived from an electronic medical record-based surveillance network of US emergency department patients with acute respiratory illness high quality but high-charge beams.Despite this need, the acceleration of largely charged beams has been barely studied.Here we explore both experimentally and numerically the physics of highly loaded wakefield acceleration.

We find that the shape of the electron spectra is strikingly independent of the laser energy, due to the emergence of a Associations of time spent on different types of digital media with self-rated general and mental health in Swedish adolescents saturation effect induced by beamloading.A transition from quasi-Maxwellian spectra at high plasma densities to flatter spectra at lower densities is also found, which is shown to be produced by the wakefield driven by the electron bunch itself after the laser depletion.
