Summary[edit]

Description
English: Beam of cathode rays (electrons) moving in a circle in a magnetic field (cyclotron motion). The electrons are produced by an electron gun at bottom, consisting of a hot cathode, a metal plate heated by a filament so it emits electrons, and a metal anode (right) at a high voltage with a hole which accelerates the electrons into a beam. Cathode rays are normally invisible, but enough air has been left in the tube so that the air molecules glow pink from fluorescence when struck by the fast-moving electrons.
Français : Faisceau d'électrons se déplaçant en cercle dans un champ magnétique (effet cyclotron). La lumière est due à l'excitation des atomes de gaz présents dans l'ampoule.
Polski: Wiązka elektronów poruszających się po orbicie kołowej w stałym polu magnetycznym. Świecenie wywołane jest wzbudzeniami atomów gazu w bańce.
Português: Feixe de eletrons movendo em circulo sob atuação de um campo magnético (cyclotron motion). A luz é causada pela exitação dos atomos de gás no bulbo.
