Abstract
The new heavy-ion storage ring project Rare-RI Ring at the RIKEN RI Beam Factory launched in 2012 aims at precision isochronous mass spectrometry for single ions of exotic nuclides. To precisely tune the storage-ring ion optical conditions to the isochronous field setting, Schottky noise pick-up technique will be employed. Pillbox-type resonant cavity, similar to the Schottky pick-up system successfully operating at the experimental storage ring ESR at GSI, is adopted for the pick-up probe. To determine the design values of the cavity, we systematically performed a simulation study of three-dimensional electromagnetic field calculations in the high frequency region. High shunt impedance obtained in the simulation will enable us to detect stored single ions with charge down to qâ15.
