Electron Rephasing in a Laser-Wakefield Accelerator.
An important limit for energy gain in laser-plasma wakefield accelerators is the dephasing length, after which the electron beam reaches the decelerating region of the wakefield and starts to decelerate. Here, we propose to manipulate the phase of the electron beam in the wakefield, in order to bring the beam back into the accelerating region, hence increasing the final beam energy. This rephas...
متن کاملPositron Production in a Plasma Wakefield Accelerator
In a visit on Oct. 28, 1996 to the Center for Ultrafast Optical Studies at U. Michigan I had interesting conversations with Gerard Mourou and Don Umstadter about possible mechanisms for positron production in a plasma that is illuminated with a strong laser. I argue that positron production via a trident process (which includes Bethe-Heitler pair production) involving an isolated nucleus is pos...
متن کاملA Meter-Scale Plasma Wakefield Accelerator
Plasma wakefield accelerators (PWFA) have recently shown substantial progress, attaining accelerating fields of more than 30 GV/m. The goal of the present experiment is to show that such accelerating fields can be sustained over the scale of a meter, resulting in a total energy gain comparable to the entire SLAC linear accelerator. We also seek to determine which factors limit the length of the...
متن کاملLaser Wakefield Accelerator Experiments at LBNL
The status is presented of the laser wakefield acceleration research at the 1'OASIS laboratory of the Center for Beam Physics at LBNL. Experiments have been performed on laser driven production of relativistic electron beams from plasmas using a high repetition rate (10 Hz), high power (10 TW) Tksapphire (0.8 jim) laser system. Large amplitude plasma waves have been excited in the self-modulate...
متن کاملIonization induced trapping in a laser wakefield accelerator.
Experimental studies of electrons produced in a laser wakefield accelerator indicate trapping initiated by ionization of target gas atoms. Targets composed of helium and controlled amounts of various gases were found to increase the beam charge by as much as an order of magnitude compared to pure helium at the same electron density and decrease the beam divergence from 5.1+/-1.0 to 2.9+/-0.8 mr...
