Abstract

PERFECCIONAMIENTOS EN UN TUBO DE RAYOS CATODICOS. CON EL FIN DE REDUCIR LA DEGRADACION DE CONTRASTE EN UN TUBO (10) DE RAYOS CATODICOS PLANO EXPLORADO ELECTROSTATICAMENTE QUE TIENE UN MULTIPLICADOR (44) DE ELECTRONES DE PLACA DE CANAL DEBIDO A ELECTRONES (46) DE RETRODISPERSION QUE ENTRAN EN CANALES ALEJADOS DE SU ORIGEN SE APLICAN UN RECUBRIMIENTO DE UN MATERIAL QUE TIENE UN BAJO COEFICIENTE DE RETRODISPERSION SOBRE LA ENTRADA DEL MULTIPLICADOR (44) DE ELECTRONES ENTRE LAS ABERTURAS DEL MISMO. LA TEXTURA SUPERFICIAL DEL MATERIAL DEBERA SER MICROSCOPICAMENTE RUGOSA. EL MATERIAL PUEDE APLICARSE AL PRIMER DINODO O A UN ELECTRODO CONECTADO ELECTRICA O FISICAMENTE AL PRIMER DINODO.
