PASAISEAU, France, Dec. 8, 2006 -- A team of French researchers said they have developed a compact laser-plasma accelerator that uses two colliding laser pulses to produce highly stable and reproducible electron streams. High-energy particle accelerators, which can generate focused beams of highly energetic electrons, currently exist only in large-scale facilities like the Stanford Linear Accelerator Center (SLAC) in California, the International Linear Collider (ILC) at Fermilab outside Chicago and CERN, the European Organization for Nuclear Research, in Geneva, Switzerland. But a team of researchers from the Optical...Read full article

    beam
    1. A bundle of light rays that may be parallel, converging or diverging. 2. A concentrated, unidirectional stream of particles. 3. A concentrated, unidirectional flow of electromagnetic waves.
    electron
    A charged elementary particle of an atom; the term is most commonly used in reference to the negatively charged particle called a negatron. Its mass at rest is me = 9.109558 x 10-31 kg, its charge is 1.6021917 x 10-19 C, and its spin quantum number is 1/2. Its positive counterpart is called a positron, and possesses the same characteristics, except for the reversal of the charge.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
