Collimated fast electron beam generation in critical density plasma

A Reflex Electron Beam Discharge as a Plasma Source for Electron Beam Generation

A reflex electron beam glow discharge has been used as a plasma source for the generation of broad-area electron beams. An electron current of 120 A ( 12 A/cm2) was extracted from the plasma in 10 ps pulses and accelerated to energies greater than 1 keV in the gap between two grids. The scaling of the scheme for the generation of multikiloamp high-energy electron beams is discussed. E HAVE demo...

Fast-electron self-collimation in a plasma density gradient

Electron Beam Generation in Tevatron Electron Lenses

New type of high perveance electron guns with convex cathode has been developed. Three guns described in this article are built to provide transverse electron current density distributions needed for Electron Lenses for beam-beam compensation in the Tevatron collider. The current distribution can be controlled either by the gun geometry or by voltage on a special control electrode located near ...

Ultracold electron bunch generation via plasma photocathode emission and acceleration in a beam-driven plasma blowout.

Beam-driven plasma wakefield acceleration using low-ionization-threshold gas such as Li is combined with laser-controlled electron injection via ionization of high-ionization-threshold gas such as He. The He electrons are released with low transverse momentum in the focus of the copropagating, nonrelativistic-intensity laser pulse directly inside the accelerating or focusing phase of the Li blo...
