Accelerator for Medical Applications and Electron Acceleration by Laser Plasma

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...

Electron acceleration by a laser pulse in a plasma.

132 LLE Review, Volume 67 The motion of a charged particle in an electromagnetic field is a well-known paradigm of physics.1,2 Suppose that the field is associated with a laser pulse of finite extent propagating in a vacuum. As the pulse overtakes the particle, the particle gains energy and momentum at the expense of the pulse. At the peak of an intense pulse, the particle has considerable (lon...

Resonantly laser-driven plasma waves for electron acceleration.

Laser Electron Accelerator

An intense electromagnetic pulse can create a weak of plasma oscillations through the action of the nonlinear ponderomotive force. Electrons trapped in the wake can be accelerated to high energy. Existing glass lasers of power density lotsW/cm shone on plasmas of densities 10 8 cm can yield gigaelectronvolts of electron energy per centimeter of acceleration distance. This acceleration mechanism...

Developments of electron and proton acceleration using Laser-plasma Interaction

With the development in ultra-short, ultra-intense laser technology, the potential of inventing novel table-size charged particle accelerators using laser-plasma interaction has attracted a lot of attentions due to its advantages comparing to classical accelerators. The accelerators have broad application aspects, such as medical imaging, cancer therapy, fast ignition in inertial fusion, and pr...
