2. A machine used to increase the velocity, and hence the kinetic energy, of subatomic particles or nuclei; usually, in preparation for collision with a target.
Stepping on the accelerator and moving at great speed is often an exhilarator to people; that is, until they get caught in a speed trap.
2. A machine that increases the energy levels of electrons in order to produce a beam of highly charged particles.
2. An electrical device that uses an electrostatic field to accelerate charged particles to high velocities in a vacuum.
3. Any machine that produces electric charges by friction or, more commonly, electrostatic induction.
4. A high-voltage generator in which electric charges are generated by friction or induction, then transferred mechanically to an insulated electrode to build up a voltage which may be as high as nine mega volts.
5. An apparatus for producing up to several million volts of electrostatic energy by successive accumulation of small static charges on an insulated high-voltage metal collector.
2. A linear accelerator in which ions are accelerated by an electric field in a standing-wave pattern that is set up in a resonant cavity by external oscillators or amplifiers.
In one version, heavy negatively charged ions are accelerated through one potential difference before being stripped of more electrons and accelerated again in a system using two or more Van de Graaff generators.
Developed by U.S. physicist Robert J. Van de Graaff, 1901-1967; a Van de Graaff generator is an electrostatic generator in which high voltages are produced by a moving belt of insulating material that collects electric charges by induction and discharges them inside a large spherical electrode; used for accelerating electrons, protons, and other nuclear particles.
2. The gas pedal, attached to the throttle in the carburetor or fuel-injection system.
Investment will fall simply because output grows at a slower rate. For investment to remain stable, output growth must be constant.
