Abstract

Un método de fabricar una fuente de electrones de emisión de campo para un tubo de rayos catódicos, caracterizado porque el emisor de cátodo filamentario se forma a partir de un filamento de carbono cristalino sumergiendo un extremo del filamento en un baño conductor y haciendo pasar entonces una corriente a través del filamento y el baño conductor.
