Some particle-beam weapons have potential practical applications, e.g. as an antiballistic missile defense or detection system. They have been known by several names: particle accelerator guns, ion cannons, proton beams, lightning rays, rayguns, etc. The concept of particle-beam weapons comes from sound scientific principles and experiments.

2003年10月17日 · KUMATORI, JAPAN— On the grounds of Kyoto University's Research Reactor Institute, workers have dug into a hillside to give a 30-year-old experimental nuclear reactor an …

In the 1944 SF story “Off the Beam” by George O. Smith, an electron gun is constructed along the length of a spaceship. In order to avoid being constrained by a net charge imbalance, it is built to also fire the same number of protons in the other direction, dissipating the mass of the “cathode”.

The possibility is examined of achieving space charge neutralization of ion beams within d-c accelerator tubes, particularly with a view to obtaining intense proton beams for injection devices. A design for an accelerating electrode is proposed which should enable neutralization to be obtained over the major part of the trajectory.

2024年10月10日 · Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have designed and tested the world’s highest voltage polarized electron gun, a key piece of technology needed for building the world’s first fully polarized Electron-Ion Collider (EIC).

2017年3月9日 · A description of the working principles of an electron gun, plus a few demonstrations.

2008年8月7日 · A magnetically insulated pulsed proton gun is described that provides an extracted parallel beam of annular cross section for microsecond pulse lengths. In initial tests, time‐averaged currents of 5 kA and current densities of 50 A/cm 2 …

Proton weapons. Proton weapons are usually referred to as "rafflurs" because of their development designation, Rapid Fluctuating Ray. All proton beams are opaque green and appear to send powerful energy waves streaking back and forth to the target.

2017年9月19日 · An electron is captured by the defect—think of this as pulling back the hammer of a gun. Then the trigger is pulled, which sets the triggering mechanism in motion, throwing the hammer against ...
