Using non-destructive Schottky detectors, precise determination of masses and lifetimes of exotic nuclear species and their isomeric states can be performed in heavy ion storage rings. Single ion sensitivity has regularly been achieved in the past using resonant cavity pick-ups. New designs are targeting an increase in measurement accuracy by additionally measuring particle position in the dispersive section of the storage ring. In this work, we report on the latest progress on the development of new position sensitive cavity pickup detectors.
