Generation of Attosecond Electron Bunches
Ultra-fast science is an important new research frontier that is driving the development of novel sources for generation of extremely short x-ray and electron pulses. Recent advances in femtosecond lasers have stimulated development of femtosecond x-ray sources that allow the study of matter at the time scale shorter than period of oscillations of atoms in molecules, ∼ 100 fs. The next breakthr...
متن کاملLow-emittance electron bunches from a laser-plasma accelerator measured using single-shot x-ray spectroscopy.
X-ray spectroscopy is used to obtain single-shot information on electron beam emittance in a low-energy-spread 0.5 GeV-class laser-plasma accelerator. Measurements of betatron radiation from 2 to 20 keV used a CCD and single-photon counting techniques. By matching x-ray spectra to betatron radiation models, the electron bunch radius inside the plasma is estimated to be ~0.1 μm. Combining this w...
متن کاملLaser Plasma Electron Linear Accelerator
The generation of an ultrashort relativistic electron bunch from a strong laser-plasma interaction have been studied by particle-in-cell simulations and observed experimentally. The electron beam was generated from the plasma created by focusing a Ti: sapphire 12 TW (tera watt) laser pulse at the edge of helium gas jet expanded into the vacuum from a pulsed supersonic nozzle. The laser pulse du...
متن کاملExperimental Results of a Plasma Wakefield Accelerator Using Multiple Electron Bunches
We present some preliminary experimental results of a plasma wakefield accelerator technique which utilizes multiple electron bunches in order to drive a plasma wave. The experiments were performed at the Accelerator Test Facility of Brookhaven National Laboratory where 5 8 equidistant bunches with a spacing that was varied between 100 250 m were fed into a 6 mm long capillary discharge plasma....
متن کاملFeasibility of a Plasma-Filled Inverse Free Electron Laser Accelerator
A high power millimeter (mm) wave, in the presence of a magnetic wiggler, produces a large longitudinal ponderomotive force that can accelerate electrons. When a plasma of density n ~ ncr, where ncr is critical density, is introduced in the interaction region, the ponderomotive force resonantly drives a plasma wave that accelerates electrons to higher energies. However, propagation of the mm wa...
