We show that a short relativistic electron beam propagating in a plasma with a density gradient perpendicular to the direction of motion generates a wakefield in which a witness bunch experiences a transverse force. A density gradient oscillating along the beam path would create a periodically varying force—an undulator, with an estimated strength of the equivalent magnetic field more than 10 T. This opens an avenue for the creation of a high-strength, short-period undulator, which eventually…

If a charged particle bunch propagates near a plasma-vacuum boundary, it excites a surface wave and experiences a force caused by the boundary. For the linearly responding plasma and

Plasma electron trapping and acceleration in a plasma wake field using a density transition.

A new scheme for plasma electron injection into an acceleration phase of a plasma wake field is presented. In this scheme, a single, short electron pulse travels through an underdense plasma with a

Plasma undulator based on laser excitation of wakefields in a plasma channel.

An undulator is proposed based on the plasma wakefields excited by a laser pulse in a plasma channel and can be submillimeter, while preserving high undulator strength.

Plasma-density-gradient injection of low absolute-momentum-spread electron bunches.

Transition radiation measurements combined with simulations indicated that the bunches can be used as a wakefield accelerator injector to produce stable beams with 0.2 MeV/c-class momentum spread at high energies.

Plasma Focusing for High-Energy Beams

We analyze the self-focusing effect of a relativistic electron or positron beam traversing through a thin slab of plasma in a linearized fluid theory, and show that the effect is very strong. The

Plasma wave undulator for laser-accelerated electrons

Laser-plasma accelerators have become compact sources of ultrashort electron bunches at energies up to the gigaelectronvolt range thanks to the remarkable progress made over the past decade. A direct

High-efficiency acceleration of an electron beam in a plasma wakefield accelerator

This acceleration of a distinct bunch of electrons containing a substantial charge and having a small energy spread with both a high accelerating gradient and a high energy-transfer efficiency represents a milestone in the development of plasma wakefield acceleration into a compact and affordable accelerator technology.

Analytic model of electromagnetic fields around a plasma bubble in the blow-out regime

An analytic model of the electric and magnetic fields surrounding the nonlinear plasma “bubble” formed around the high-current electron bunch in a plasma wakefield accelerator is developed. The

A nonlinear kinetic theory for multidimensional plasma wave wakes with phase velocities near the speed of light is presented. This theory is appropriate for describing plasma wakes excited in the

GigaGauss solenoidal magnetic field inside bubbles excited in under-dense plasma

This method produces large solenoidal fields that move with the driving laser pulse and are collinear with the accelerated electrons, opening up novel opportunities for designs of the light sources, free electron lasers, and high energy colliders based on laser plasma acceleration.

An ultracompact X-ray source based on a laser-plasma undulator.

It is demonstrated that this system can produce bright, collimated and tunable beams of photons with 10-100 keV energies, which opens a path towards a new generation of compact synchrotron sources based on nanostructured plasmas.
