Building accelerator afterburners with plasma.

Particle colliders are pushing the limits of economic and political feasibility. Already, the next generation of planned linear colliders is tens of kilometers long; a planned circular collider is 100 kilometers in circumference. Such massive projects will take years to build and strain government purse strings. And yet, scientists are intent on pursuing even higher energies to reveal more of t...

A Plasma Wake Field Accelerator*

Laser 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...

The Plasma Wake Field Accelerator*

A new scheme of electron acceleration, employing relativistic electron bunches in a cold plasma, is analyzed. The wake field of a leading bunch is derived in a single-particle model. We then extend the model to include finite bunch length effect. In particular, we discuss the relation between the charge distributions of the driving bunch and the energies transformable to the trailing electrons....
