英文摘要	As there is no 79Se standard sample for measurement of 79Se, the characterizations of 79Se are conducted by isotope ratio of 78Se/Se or 80Se/Se since the abundances of 78Se and 80Se are well known. However, beams of 78Se and 80Se both exceed the upper limit of semiconductor detector resulting in measurement failure. As a result, attenuators were introduced into the CIAE-AMS system with the aim to measure the 79Se. The results indicate that the beam of 78Se and 80Se is decreased into the detecting range of semiconductor detector by two attenuators, which would improve measurement sensitivity and efficiency significantly. In addition, the uncertainty of measurement is reduced greatly and it lays the foundation for the accuracy measurement of the half life of 79Se.
