A particle beam is a stream of charged or neutral particles.In particle accelerators, these particles can move with a velocity close to the speed of light. [1] There is a difference between the creation and control of charged particle beams and neutral particle beams, as only the first type can be manipulated to a sufficient extent by devices based on electromagnetism.
Bunched beams are most common in modern facilities, since the most modern particle accelerators require bunched beams for acceleration. [2] Assuming a normal distribution of particle positions and impulses, a charged particle beam (or a bunch of the beam) is characterized by [3] the species of particle, e.g. electrons, protons, or atomic nuclei
A particle-beam weapon uses a high-energy beam of atomic or subatomic particles to damage the target by disrupting its atomic and/or molecular structure. A particle-beam weapon is a type of space-based directed-energy weapon, which directs focused energy toward a target using atomic scale particles.
Another beam-pushed concept would be to use a magnetic sail or MMPP sail to divert a beam of charged particles from a particle accelerator or plasma jet. [14] Landis proposed a particle beam pushed sail in 1989, [ 7 ] and analyzed in more detail in a 2004 paper. [ 15 ]
The particle beam passes through a series of ring-shaped ferrite cores standing one behind the other, which are magnetized by high-current pulses, and in turn each generate an electrical field strength pulse along the axis of the beam direction.
Particle radiation is the radiation of energy by means of fast-moving subatomic particles. Particle radiation is referred to as a particle beam if the particles are all moving in the same direction, similar to a light beam. Due to the wave–particle duality, all moving particles also have wave character. Higher energy particles more easily ...
Charged particle beam, a spatially localized group of electrically charged particles Cathode ray, or electron beam or e-beam, streams of electrons observed in discharge tubes; X-ray beam, a penetrating form of high-energy electromagnetic radiation; Molecular beam, a beam of particles moving at approximately equal velocities
Particle beam cooling is the process of improving the quality of particle beams produced by particle accelerators, by reducing the emittance. Techniques for particle beam cooling include: [1] Stochastic cooling [2] Electron cooling [3] [4] Ionization cooling; Laser cooling [5] Radiation damping; Buffer-gas cooling within RF quadrupoles
