Abstract
EQUIPO PARA LA DETECCION DEL DECAIMIENTO EN EL TIEMPO DE NEUTRONES TERMICOS EN UNA FORMACION TERRESTRE. EL EQUIPO DE INTERIOR, SITUADO EN UNA SONDA (10) HERMETICA Y RESISTENTE A LA PRESION Y TEMPERATURA, SE COMPONE DE UN GENERADOR DE NEUTRONES PULSADOS (22), CON SU CIRCUITO DE CONTROL (30) Y UNOS DETECTORES DE RADIACION (24, 26), LOS CUALES APLICAN LA RADIACION RECIBIDA A UN CIRCUITO DE HABILITACION DE SEÑALES (32). LA SONDA (10) ESTA SUSPENDIDA EN EL POZO (12) A ESTUDIAR POR UN CABLE (14) QUE SE UTILIZA PARA LA TRANSMISION DE DATOS AL EQUIO DE SUPERFICIE, CONSTITUIDO POR UN RECEPTOR (36), UN CONTADOR (38), UN ALMACENADOR DE DATOS INTERMEDIOS (40) Y UN PROCESADOR DE DATOS (42), CON UN REGISTRADOR (44).
