Record 1 2013-10-02

English

Subject field(s)
  • Vacuum Tubes (Electronics)
  • Electromagnetism
  • Television (Radioelectricity)
DEF

The moving of the electron beam by means of a magnetic field produced by a coil around the neck of the cathode-ray tube.

CONT

Magnetic deflection of the electron beam can be used instead of electrostatic deflection. A magnetic deflecting field is established in the tube just past the electron gun to react with the magnetic field associated with the electron-beam current, producing a force that deflects the electrons at right angles to both the beam-current axis and the deflection field.

OBS

Linear motion is produced by a sawtooth current through the coil.

French

Domaine(s)
  • Tubes et lampes (Électronique)
  • Électromagnétisme
  • Télévision (Radioélectricité)
CONT

Application : déviation magnétique d'un faisceau d'électrons [...] Ce mode de déflexion est utilisé dans les tubes de télévision [...] car il permet d'obtenir des déviations angulaires beaucoup plus grandes que celles fournies par une déviation électrostatique [...]

English

Subject field(s)
  • Vacuum Tubes (Electronics)
DEF

An electron gun that has high total perveance and produces a hollow beam of microwave radiation in the frequency range 1-40 gigahertz, which is parallel to the axis of a magnetic field.

Record 3 2005-06-28

English

Subject field(s)
  • Guns (Land Forces)
  • Advanced Technology Weapons
DEF

[A] device designed to launch small projectiles at high velocities by converting electrical energy into kinetic energy.

CONT

The Defense Department is exploring the hypervelocity electromagnetic rail gun. The rail gun uses an extremely powerful magnetic field to launch projectiles at speeds of miles per second.

Key term(s)
  • electro-magnetic railgun
  • electro-magnetic rail gun
  • electro-magnetic launcher

French

Domaine(s)
  • Canons (Forces terrestres)
  • Armes de haute technicité

Spanish

Campo(s) temático(s)
  • Cañones (Ejército de tierra)
  • Armas de tecnología avanzada
OBS

Su funcionamiento, que pasamos a detallar, se basa en los principios que rigen el comportamiento de los campos magnéticos y las corrientes eléctricas. Por todos es sabido que los polos homólogos de los campos magnéticos se repelen. Si acercamos los dos polos N de dos imanes estos intentaran separarse. Si llevamos este sistema a sus extremos nos da lugar a un arma excepcional. Su funcionamiento es simple: Dos raíles (De ahí su otro nombre "Arma de rail") conectados a una potente fuente de pulsos eléctricos convenientemente posicionados en el entorno de un poderoso campo magnético. Mediante un sistema neumático se lanza entre esos raíles un proyectil cuya superficie sea conductora y haga contacto con los raíles a una velocidad considerable cortocircuitándolos y formando a su alrededor un nuevo campo magnético que será intensamente repelido por el otro campo "local" haciendo que acelere excepcionalmente y que el proyectil sea proyectado fuera del sistema a una gran velocidad.

Record 5 1999-06-04

English

Subject field(s)
  • Magnetism
  • Vacuum Tubes (Electronics)
DEF

An electron gun that produces an initially convergent electron beam by the use of electrostatic fields alone.

CONT

The standard geometry of a rotationally symmetric Pierce gun is finally revised to allow for the addition of an external magnetic field.

French

Domaine(s)
  • Magnétisme
  • Tubes et lampes (Électronique)
DEF

Canon électronique qui, en n'utilisant que des champs électrostatiques, donne un faisceau électronique initialement convergent.
