Beam of electrons emitted by an electron gun moving in a circle in a magnetic field (cyclotron motion). The electrons themselves are invisible, but their path is made visible by residual air molecules which glow by fluorescence when struck by the fast-moving electrons. ---------------------- Un faisceau délectrons défléchis par un champ magnétique forme un cercle par effet cyclotron. La lueur provient de lexcitation des atomes gazeux prisonniers de lampoule.
