Plasma Wakefield Experiments
We discuss the recent experiments in the field of Plasma Wakefield Acceleration (PWFA), with emphasis on the FNAL experiment. After completion of this work, the next round of experiments will need to push the envelope on accelerating gradient, interaction length, stability, and accelerated charge. We present theoretical results dealing with plasma accelerator performance in the limit of high dr...
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 کاملDielectric Wakefield Accelerator Experiments at Atf*
Dielectric wakefield acceleration (DWA) presents us with means to achieve the accelerating gradient high above the limits of conventional accelerators. In a typical DWA scheme a higher energy lower charge main bunch is accelerated in the wakefield produced by a preceding lower energy higher charge drive bunch inside of a hollow metal-encapsulated dielectric tube. To make use of as much energy o...
متن کاملUltra-High Gradient Dielectric Wakefield Accelerator Experiments
Ultra-high gradient dielectric wakefield accelerators are a potential option for a linear collider afterburner since they are immune to the ion collapse and electron/positron asymmetry problems implicit in a plasma based afterburner. The first phase of an experiment to study the performance of dielectric Cerenkov wakefield accelerating structures at extremely high gradients in the GV/m range ha...
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...
