Abstract

TUBO DE CAMARA DE TELEVISION. COMPRENDE UNA AMPOLLA DE VIDRIO CON VACIO INTERIOR, CAÑON ELECTRONICO DIODICO PARA LA GENERACION DE UN HAZ ELECTRONICO. EL CAÑON INCLUYE, CENTRADOS A LO LARGO DE UN EJE Y DE FORMA SUCESIVA, UN CATODO CON SUPERFICIE EMISORA Y ANODO CON SUPERFICIE PLANA TAMBIEN PERPENDICULAR AL EJE. EN SU CENTRO POSEE UNA PARTE QUE SE EXTIENDE EN LA DIRECCION DEL CATODO, CONVERGIENDO SUS PAREDES INTERIOR Y EXTERIOR HACIA EL EJE. LA PARED EXTERIOR CAMBIA A UNA SUPERFICIE APICAL, PARALELA A LA SUPERFICIE EMISORA, CON ABERTURA CENTRAL. UN ELECTRODO PLANO CONECTADO AL ANODO SE DISPONE A UNA DISTANCIA D DE LA SUPERFICIE EN LA CARA DEL ANODO ALEJADA DEL CATODO. ESTA DISTANCIA OSCILA ENTRE 4 Y 25 VECES LA DISTANCIA EXISTENTE ENTRE SUPERFICIE APICAL Y SUPERFICIE EMISORA.TELEVISION CAMERA TUBE. IT INCLUDES A GLASS AMPOULE WITH INTERIOR VACUUM, ELECTRONIC DIODIC BARREL FOR THE GENERATION OF AN ELECTRONIC BEAM. THE BARREL INCLUDES, CENTERED ALONG AN AXIS AND IN A SUCCESSIVE WAY, A CATHODE WITH AN EMITTING SURFACE AND ANODE WITH A FLAT SURFACE ALSO PERPENDICULAR TO THE AXIS. IN ITS CENTER IT HAS A PART THAT EXTENDS IN THE DIRECTION OF THE CATHODE, CONVERGING ITS INTERIOR AND EXTERIOR WALLS TOWARDS THE AXIS. THE EXTERIOR WALL CHANGES TO AN APICAL SURFACE, PARALLEL TO THE EMITTING SURFACE, WITH CENTRAL OPENING. A FLAT ELECTRODE CONNECTED TO THE ANODE IS POSITIONED AT A DISTANCE D FROM THE SURFACE ON THE ANODE FACE AWAY FROM THE CATHODE. THIS DISTANCE RANGES BETWEEN 4 AND 25 TIMES THE EXISTING DISTANCE BETWEEN APICAL SURFACE AND EMISSIONING SURFACE.
