摘要：
The present detection limit for Hf-182 at CIAE HI-13 AMS systems could not satisfy various applications (e. g. detection of a nearby supernovae signal). Therefore, techniques were developed in this work to improve the AMS measurement of Hf-182 mainly on building a new injector and using a method that based on solid-phase reaction for the preparation of HfF4 samples from HfO2. The experimental results show that mass resolution of the injector can reached 630, and the F-/O- and beam current of (HfF5-)-Hf-180 for HfF4 samples produced by dry method is about 2-3 times and 1.5 times of that by previously method, respectively.
