Electron Acceleration in the Heliosphere
Space Science Reviews, 2001We review the evidence for electron acceleration in the heliosphere putting emphasis on the acceleration processes. There are essentially four classes of such processes: shock acceleration, reconnection, wave particle interaction, and direct acceleration by electric fields.

Review of Scientific Instruments, 1948
The theory, design, and some experimental results relative to linear electron accelerators are discussed. It is shown that, though the orbits are unstable, this instability is so small as to be negligible in general, provided the electrons are injected at relativistic velocities. Likewise, space-charge spreading may be neglected.

Coherent nanophotonic electron accelerator
Nature, 2023Particle accelerators are essential tools in a variety of areas of industry, science and medicine1-4. Typically, the footprint of these machines starts at a few square metres for medical applications and reaches the size of large research centres. Acceleration of electrons with the help of laser light inside of a photonic nanostructure represents a ...

Collective Accelerator for Electrons
Physical Review Letters, 1985A concept for collective acceleration and focusing of a high-energy electron bunch is presented. The scheme combines an intense relativistic electron beam propagating in low-density gas with a trailing picosecond laser pulse for prompt photoionization of the gas to create the intense collective fields.

Laser acceleration of electrons in vacuum
Physical Review E, 1995Several features of vacuum laser acceleration are reviewed, analyzed, and discussed, including electron acceleration by two crossed laser beams and acceleration by a higher-order Gaussian beam. In addition, the vacuum beat wave accelerator (VBWA) concept is proposed and analyzed. It is shown that acceleration by two crossed beams is correctly described

A Magnetic Resonance Accelerator for Electrons
Nature, 1948IN his paper, "A New Method of Acceleration of Relativistic Particles", Veksler1 proposed two methods of overcoming the limitation of the cyclotron due to the relativistic increase of the mass of the particle. One of these is the synchrotron, now well known ; and the other, which has been called the microtron2 and is essentially an electron cyclotron ...

The Yale Linear Electron Accelerator
Review of Scientific Instruments, 1951The Yale linear accelerator has been designed to produce large currents of 10-Mev electrons by the use of independent resonant cavities driven by 500-kw triode power amplifiers. The design principles and construction methods used for this recently completed machine and data on its performance are presented.

Inverse-bremsstrahlung electron acceleration
Physical Review Letters, 1991A single-particle computation, simple analysis, and a particle simulation show that energy gain of an electron in a vacuum is possible using a laser and with a weak perpendicular static electric field (${\mathit{E}}_{\mathrm{app}}$). This simple system does not need any structure to accelerate the electron.

The Microwave Linear Electron Accelerator
The British Journal of Radiology, 1949The present interest in linear accelerators for nuclear physics and medical use, which has arisen from the development of microwave valves and waveguide techniques during the war, is reviewed, and the various types of microwave linear accelerator are briefly described.
