| Outline of Final Research Achievements |
In this study, we developed a window-less gas-cell cooler-buncher and an ion trap for precision experiments for low-energy unstable nuclei.
We optimized an RF carpet dedicated to the gas cell filled with 2 mbar helium gas and developed a PCB-based ion trap for ion bunching. For the RF carpet, we tuned RF resonance circuit to obtain a frequency of 13 MHz even for the large diameter of 200 mm which fully covers the cross section of the gas cell. For the ion trap, we developed thick PCB electrodes which has a printed pattern of segmented electrodes. We tested the transport and the bunching efficiency with wide mass-ranged ions (40~250) and could obtain the efficiency of more than 90%. The GCCB has universality, simple structure, and high efficiency, therefore it is planed to install for other low-energy nuclear physics facilities.
