AB - Rare-RI Ring *, ** is a storage ring dedicated for precise mass measurements of unstable nuclei to make clear the astrophysical r-process path. We employ the Isochronous mass spectrometry method in the order of 10⁻⁶. For precise tuning of the isochronous field, we developed a resonant Schottky pick-up which had a resonant cavity. We acquired the quantities by the offline test: shunt impedance, and unloaded quality factor. Using the quantities, we estimated the output signal power which is corresponding to a single ion with charge q on resonance ***. Comparing to thermal noise, present Schottky pick-up can detect a single ion with charge over 16. In June, we carried out the first commissioning of Rare-RI Ring using 78Kr³⁸⁺ beam with the energy of 167 MeV/nucleon. By using the individual injection method with the fast kicker system, we succeeded in injecting, storing, and extracting 78Kr³⁸⁺ ions. The Schottky pick-up successfully detected single 78Kr³⁸⁺ ions. Also we confirmed that 78Kr³⁸⁺ was stored for more than 2 seconds in a vacuum of 10-5 Pa. In this contribution, we will present recent status of the Schottky pick-up focusing on the results of the experiment.
