摘要：

A 14-MeV FNAA system for oxygen analysis has been developed in which both data collection and processing are controlled by a PC-type computer equipped with an ORTEC ACE(TM)-MCS multichannel scaler card. A single loop pneumatic transfer system automatically moves samples to the irradiation position and returns them to a counting position between two NaI(Tl) detectors operated through a summing amplifier. Software for data processing has been developed. Dead times of the BF3 neutron monitor and gamma-ray counting system has been separately determined. Results are presented for a variety of standard samples.
