Abstract

TUBO DE RAYOS CATODICOS. DENTRO DE UNA AMPOLLA DE VACIO (1) UN CAÑON ELECTRONICO (5) GENERA UN HAZ (6, 7, 8) QUE SE ENFOCA SOBRE EL BLANCO (10) POR MEDIO DE UNA LENTE ELECTRONICA ACELERADORA. ESTA LENTE COMPRENDE DOS ELECTRODOS SEPARADOS ENTRE SI (HUELGO DE LA LENTE). UNA LAMINA METALICA ESTA SITUADA DENTRO DEL SEGUNDO ELECTRODO, CON LA INTENCION DE CORREGIR LA ABERRACION ESFERICA DEL HAZ ELECTRONICO, LO QUE SE DICE OCURRIR CUANDO LA LAMINA ES PLANA Y ESTA DISPUESTA EN UNA POSICION TAL QUE SE CUMPLE QUE 0,25 H L/R H 2,0, SIENDO L LA DISTANCIA DE LA LAMINA METALICA AL HUELGO DE LA LENTE, Y R EL RADIO DE LA PARTE DEL SEGUNDO ELECTRODO DENTRO DE LA CUAL (O ADOSADA A LA CUAL) SE DISPONE LA LAMINA METALICA.
