Abstract
SE DESCRIBE UN CAÑON ELECTRONICO DE FOCO DINAMICO QUE COMPRENDE UN MEDIO DE TRIODO PARA FORMAR INICIALMENTE HACES DE ELECTRONES Y UN MEDIO DE LENTE PRINCIPAL PARA ENFOCAR Y ACELERAR LOS HACES DE ELECTRONES POR MEDIO DE CAMPOS ELECTRICOS DINAMICOS,EN EL QUE EL MEDIO DE LENTE PRINCIPAL INCLUYE: UN ELECTRODO AUXILIAR QUE COMPRENDE TRES MIEMBROS CILINDRICOS QUE TIENEN EN EL CENTRO DE CADA UNO DE SUS CUERPOS UNA VENTANA INTRODUCTURA DE CAMPOS ELECTRICOS PARA INTRODUCIR LOS CAMPOS ELECTRICOS EN LAS DIRECCIONES VERTICAL Y HORIZONTAL, UN ELECTRODO ELIPTICO TUBULAR PARA RODEAR SENCILLAMENTE LAS VENTANAS INTRODUCTORAS DE CAMPOS ELECTRICOS DE LOS MIEMBROS CILINDRICOS. SEGUN EL PRESENTE INVENTO PUEDE EVITARSE LA INTERFERENCIA ENTRE LOS HACES ELECTRONICOS, Y MANTENERSE EL ESTADO DE ENFOQUE DE LOS HACES ELECTRONICOS EN LA CONDICION OPTIMA.
