Abstract：
In order to improve the accuracy of accelerator mass spectrometry (AMS) measurement for ¹⁸²Hf/¹⁸⁰Hf, a series of measurements have been taken in the AMS laboratory at the China Institute of Atomic Energy (CIAE). The major ones include the instantaneous monitoring of ¹⁸⁰HfF₅^- current, testing the stability of transmission, the alternate measurements of an unknown sample and standard, and the origin identification and minimization of background ¹⁸²W. The experimental details and the improvement in the measurement accuracy, as well as some useful suggestions for better satisfying the requirements of certain practical applications, are presented in this paper.
