文摘In order to reduce the systematic uncertainties caused by the sequential injection in AMS measurement of ^(182)Hf,a technique for instantaneous monitoring of off-axis∑HfF_5^- current was developed in the AMS laboratory at China Institute of Atomic Energy(CIAE).The stability and reliability of this method have been experimentally verified.As a result,the accuracy for AMS measurement of^(182)Hf was significantly improved.
