Abstract
SE RESUELVEN LOS PROBLEMAS DE TEMPERATURA DE UN ANODO REALIZANDO UN CATODO PLANO (1) INSCRITO EN UN DISPOSITIVO (8) DE FOCALIZACION GRADUADA. SE DEMUESTRA QUE EN FUNCION DE LA FORMA DE ESTE DISPOSITIVO EL CAUDAL TERMICO SOBRE EL ANODO ESTA LIMITADO POR UN VALOR DE SATURACION INFERIOR A UN LIMITE DE MANTEMIENTO TERMICO DE ESTE TUBO. PARA MEJORAR ESTE MANTENIMIENTO TERMICO DEL CATODO SE REALIZA UN CATODO EN FORMA DE VIGA HUECA. ESTO LE ASEGURA UNA RIGIDEZ INHERENTE POR SU FORMA DE VIGA SIN CONFERIRLE POR OTRA PARTE LOS INCONVENIENTES DE UNA EXCESIVA INERCIA TERMICA.
