Fluctuation-induced transport in the Hall plasma accelerator

This paper considers small-amplitude fluctuations in the Hall-effect thruster. To predict which fluctuations could be important to transport, the growth of a disturbance is determined as a function of real frequency and propagation angle. In the simple case, strong growth is predicted for disturbances that are azimuthal. In the general case, strong growth is predicted for various propagation an...

The Magnetic Interference Hall Accelerator

This paper introduces a new concept for the magnetic field in a Hall-effect thruster. The Magnetic Interference Hall Accelerator (MIHA) uses independent magnetic circuit elements to put its peak magnetic field outside its exit plane. As a result, the zone of minimum electron mobility is outside its exit plane, as well as its ion acceleration zone. Wall-effects are reduced, and ion bombardment o...

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...
