Abstract

La presente invencion se refiere a una estructura calentada directamente de un cátodo, que incluye una pastilla porosa dentro de la cual se impregna el material del cátodo, filamentos conectados con la pastilla porosa, un soporte para soportar el filamento y un bloque de aislamiento para proporcionar apoyo al soporte, en donde los filamentos están soportados sobre la pastilla porosa por un elemento auxiliar unico o por varios (dos) elementos auxiliares. La estructura de soporte es muy fuerte y la calidad y la productividad pueden ser mejoradas ampliamente por medio de la mejora del proceso de soldadura.
