Abstract

Visualizzatore piatto ad emissione di campo, avente uno spazio interno sotto vuoto in cui sono alloggiati:a) uno strato di fosfori eccitabili ed una pluralità di microcatodi, che emettono elettroni sotto lo stimolo di un elevato campo elettrico;b) una pluralità di passanti elettrici ed uno stabilizzatore di vuoto.Detto stabilizzatore di vuoto è essenzialmente costituito da uno strato poroso supportato di materiale getter non - evaporabile, avente uno spessore da 20 a 180 micrometri, alloggiato in una zona essenzialmente libera da microcatodi, da fosfori e da passanti.
