Abstract

Mejoras en los procedimientos para preparar un electrodo de emisión secundaria para funcionar en un aparato de descarga electrónica en el cual sea herido por un chorro electrónico de determinadas densidades de funcionamiento normal, caracterizado por montarse el electrodo en un receptáculo en que se produzca el vacio y bombardearas el electrodo con un chorro electrónico de densidad relativamente mayor que cualquiera de dichas densidades de funcionamiento normal.Improvements in the procedures to prepare a secondary emission electrode to function in an electronic discharge device in which it is wounded by an electronic jet of certain normal operating densities, characterized by mounting the electrode in a receptacle in which the vacuum is produced and you will bombard the electrode with an electronic jet of density relatively higher than any of these normal operating densities.
