Il s'agit d'une diode à vide entourée d'un puissant aimant permanent. La cathode, au centre, émet des électrons qui sont attirés vers une anode concentrique lorsque cette dernière est portée à un potentiel positif. Or le champ magnétique fait dévier les électrons dont la trajectoire prend la forme d'une spirale... ce qui donne lieu à des oscillations. Aussi l'anode contient des cavités résonantes qui entretiennent les oscillations dans la bande des hyperfréquences. L'énergie qui en résulte, pouvant atteindre plusieurs mégawatts, est acheminée vers l'antenne à l'aide d'un réseau de guides d'ondes. On utilise des magnétrons dans les radars et les relais hertziens.  1, record 3, French, - magn%C3%A9tron

The principle of operation for the active hydrogen maser is based upon a 5 MHz quartz crystal oscillator, phase locked to the hyperfine transition of the hydrogen atom. The atomic hydrogen signal generated within the physics package is then picked up by an antenna in the cavity and coupled to the synchronization unit, which synchronizes the 5 MHz crystal oscillator signal phase to the hydrogen signal phase producing the 5 MHz and 100 MHz spectrally pure sine-wave signal output.  2, record 7, English, - active%20hydrogen%20maser
