Abstract

Un tubo de rayos catódicos que comprenden en una ampolla con vacío interior, un cañón de electrones para generar un haz de electrones comprende. Centrados a lo largo de un eje geométrico, un cátodo, una rejilla que tiene una abertura, y un primer ánodo que tiene una abertura, después de cuya rejilla se induce una zona de cruce astigmática en el haz de electrones, caracterizado porque la zona de cruce astigmática es inducida por un campo magnético no rotacionalmente simétrico.
