[...] la production des rayons X [mettant en œuvre] un montage à anticathode [s'effectue selon le] principe [suivant] : dans un contenant scellé et sous vide, une différence de potentiel de plusieurs milliers de volts (30 à 50 kV) est imposée entre deux électrodes. Les électrons produits par un filament de tungstène chauffé vont alors être accélérés très fortement, [créant] un flux rapide d'électrons vers l'anticathode. Lorsque ces électrons vont heurter la surface de l'anticathode ils vont exciter les électrons du métal dont est constitué l'électrode, ce qui va donner naissance à un rayonnement X [...] émis via des fenêtres en béryllium (matériau transparent aux rayons X et capable de résister au vide poussé qui règne dans l'enceinte [sous vide]).

Le cyclotron [...] permet d'accélérer les particules chargées grâce à la combinaison d'un champ électrique accélérateur, d'un champ magnétique qui circularise les trajectoires dans l'enceinte sous vide et enfin d'une radiofréquence qui assure la synchronicité de l'accélération à l'entrée et à la sortie des électrodes [...] 3, record 1, French, - enceinte%20sous%20vide
