First test results of the digital data acquisition at the HORUS spectrometer

The HORUS spectrometer at the 10MV Tandem accelerator at the Institute for Nuclear Physics in Cologne consists of 14 high-purity germanium γ-detectors. To extend the experimental opportunities, the new silicon-detector array SONIC was designed, housing eight ΔE-E sandwich silicon detectors for ion spectroscopy. In order to process all 30 detector signals, the analog data acquisition was replaced by a digital one using the commercially available DGF-4C modules from the company XIA. The new data acquisition system was tested in two experiments.
