Abstract
INSTALACION Y METODO PARA MEDIR CAMPOS MAGNETICOS MUY PEQUEÑOS. PARA MEDIR VALORES DEL ORDEN 10-9 A 10-15 TESLAS ESPECIALMENTE DE ORIGEN BIOLOGICO SE DISPONE DE UNA INSTALACION CON ELECTRODOS CAPTADORES (1), UNA BOBINA AUXILIAR (2) Y UN SENSOR SUPERCONDUCTOR (3), TIPO SQUID, CON APANTALLAMIENTO MAGNETICO (5), SUMERGIDOS EN NITROGENO LIQUIDO A TEMPERATURA DE 77 K, LOS VALORES DEL SENSOR SE ENVIAN A TRAVES DE UN CABLE CRIOGENICO (8) A UN MODULO DE ACOPLAMIENTO (7) Y DE ALLI A UNA CONTROLADORA MULTICANAL (9) POR UN CABLE OPTICO (10) PARA INDICACION DE LOS VALORES DE MEDIDA EN SU PANTALLA DE PRESENTACION (11). EL METODO TIENE ETAPAS OPERATIVAS DE COLOCACION DE ELECTRODOS EN UNA MUESTRA (12) A MEDIR, DETECCION DE LOS VALORES A TRAVES DE LA BOBINA (2) Y EL SENSOR (3) CON APANTALLAMIENTO MAGNETICO A TEMPERATURAS DE 77 K, PARA PRESENTACION DE DICHOS EN UNA PANTALLA (11) CON LA AYUDA DE UN MODULO DE ACOPLAMIENTO (7) Y UNA CONTROLADORA MULTICANAL (9).
