FN Tandem accelerator at the University of Cologne (UoC)

The Institute for Nuclear Physics at the University of Cologne provides different accelerators, including a 10 MV FN-Tandem and a 6 MV Tandetron accelerator. While the latter one serves as a machine intended solely for Accelerator Mass Spectrometry (AMS) measurements, the 10 MV FN-Tandem accelerator is used for research in nuclear physics and nuclear astrophysics.

The 10 MV FN-Tandem accelerator provides beams of basically any ion-species which can form negative ions in a beam current range between a nA and μA for a consecutive duration of several days. Various experimental setups equipped with several high-purity germanium detectors as well as silicon particle detectors are used for investigations of nuclear reaction rates, nuclear lifetimes, and structures of excited states in atomic nuclei.

A low-background Counting setup that consists of 2 HPGe Clover detectors mounted in a close face-to-face geometry is available for gamma-ray counting experiments.

A fully equipped target laboratory is operational in the same department. Hence, on request, targets can be made at the University of Cologne prior to the experiments. During the last years, the number of external users varied between 1 and 4 per year. Usually, external users stay between 4 and 7 nights.

Country of Installation: Germany

Access to be provided: 480 beam time hours

A presentation introducing transnational access to this facility was given at the ChETEC-INFRA Kickoff-Meeting:
