Nuclear astrophysics studies on highly charged radionuclides benefit from accelerators with storage rings, where exotic nuclides produced with small yields can be efficiently stored. Non-destructive methods based on frequency analysis are usually used for in-fight measurements. The sensitivity of such detection systems are of great importance since number of stored ions is small. A resonant Schottky pickup with high sensitivity, built by GSI, will be applied at CSRe to study the nuclear properties of highly charged ions such as time-resolved Schottky mass spectrometry and life time measurements.
