英文摘要
Accelerator mass spectrometry (AMS) is a useful tool for low level measurement of long life radioisotopes. A high accelerator voltage is required for a sufficient isobaric separation with increase of atomic number for AMS. Calcium-41 AMS is not carried out in Japan and has a potential in dating and medical science.CaF2 sample was mixed with some materials used for a pilot beam which controls the terminal voltage of the tandem electrostatic accelerator at the University of Tsukuba. From mixed sample of CaF2, 20 nA of negative CaF3 beam was extracted. We tried to measure Ca-41 with a terminal voltage of 8 MV. The result suggests a potential for ultrasensitive analysis of Ca-41 by using high energy accelerator mass spectrometry.
