The working group considered high transformer ration schemes for an afterburner based on the design of a future linear collider. The main linac produces high charge beams of 100 GeV. A multiple stage plasma based accelerator would accelerate a portion of this beam to 500 GeV. The length of each plasma stage is expected to be of the order of a few meters while the isochronous beam transport requ...
The capability of plasmas to sustain ultrahigh electric fields has attracted considerable interest over the last decades and has given rise to laser-plasma engineering. Today, plasmas are commonly used for accelerating and collimating relativistic electrons, or to manipulate intense laser pulses. Here we propose an ultracompact plasma undulator that combines plasma technology and nanoengineerin...
Abstract. When considering intense particle or laser beams propagating in dense plasma or gas, ionization plays an important role. Impact ionization and tunnel ionization may create new plasma electrons, altering the physics of wakefield accelerators, causing blue shifts in laser spectra, creating and modifying instabilities, etc. Here we describe the addition of an impact ionization package in...
The wake fields produced by an intense, short laser pulse propagating in a plasma channel with an arbitrary density profile are investigated. Plasma channels, viewed as accelerating structures, have many desirable features that are not shared by a homogeneous plasma. Moreover, they are becoming experimentally realizable. As part of an overall program to analyze plasma channels as accelerating s...
We present a solid state accelerator concept utilizing particle acceleration along crystal channels by longitudinal electron plasma waves in a metal. Acceleration gradients of order 100 GV/cm are theoretically possible, but channeling radiation limits the maximum attainable energy to lo5 TeV for protons. Beam dechanneling due to multiple scattering is substantially reduced by the high accelerat...
Abstract Demonstrating the viability of Advanced Accelerator Concepts (AAC) relies on experimental validation. Over last three decades, U.S. has maintained a portfolio advanced and novel accelerator test facilities to support research critical AAC. The have enabled pioneering developments in wide variety beam physics, including plasma-wakefield structure-wakefield acceleration. This paper provi...
