Abstract:
A simple single anode gas ionization chamber (GIC) design for low-energy ions was developed for a compact accelerator mass spectrometer at Guangxi Normal University (GXNU-AMS) , China. This detector comprises a 50-nm silicon nitride window, an anode, a Frisch grid, and a cathode. To determine the optimal measurement conditions and to characterize the detector performance at low energy, test experiments were performed with a 239Pu/241Am α source and 3H and 14C ions at the energies of ~180 keV. The results prove that this GIC can be used for measuring ions at low energy and meets the requirements for low-energy ion measurements at GXNU-AMS.
