Abstract

La invencion se relaciona con un canon de electrones para un tubo de rayos catodicos, que comprende por lo menos un primer electrodo (G1) y un segundo electrodo (G2) para conformar y enfocar el haz de electrones emitido por un catodo (K). Estos electrodos (G1, G2) se elaboran de una aleacion no oxidante cuyo coeficiente de expansion entre 20°C y 300°C se encuentra entre 4 x 10-6/°C y 13 x 10-6/°C. Aplicacion: tubos de rayos catodicos.
