Abstract

ESTA INVENCION SE REFIERE A UNA BRIDA DE DEFLECCION (55) MONTADA SOBRE UN TUBO DE RAYOS CATODICOS (90), QUE DISPONE DE UN PAR DE POTENCIADORES DEL CAMPO HARMONICO (8A, 8B) HECHOS DE MATERIAL MAGNETICO DE ALTA PERMEABILIDAD Y COLOCADOS SOBRE LAS PARTES TRASERAS DE UNAS BOBINAS DE DEFLECCION HORIZONTAL (10A, 10B) CERCA DE LA ZONA DE ENTRADA DEL HAZ DE ELECTRONES, DE TAL MANERA, QUE PARTE DE LAS BOBINAS ESTEN INTERPUESTAS ENTRE EL POTENCIADOR DEL CAMPO MAGNETICO Y LA ZONA DEL CUELLO (33) DEL TUBO DE RAYOS CATODICOS. LOS POTENCIADORES DEL CAMPO HARMONICO (8A, 8B) REDUCEN EL ERROR DE COMA HORIZONTAL HACIENDO QUE EL CAMPO DE DEFLECCION HORIZONTAL EN LA POSICION TRASERA DE LAS BOBINAS (10A, 10B) TOME UNA FORMA ALAVEADA.
