Abstract

The data acquisition (DAQ) system of the HPGe-detector array HORUS at the Institute for Nuclear Physics At the University of Cologne is currently being updated. Instead of using analogue DAQ techniques to obtain gamma and particle spectra as well as the corresponding coincidence matrices, the 80 MHz Multichannel Digital Gamma Finder (DGF-4C Rev. F) developed by XIA, which samples the pre-amplifier signal directly, is employed. The DGF module and the new DAQ have been tested extensively and compared to the former analogue data acquisition using alpha and gamma sources and the results of these tests are presented.
