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.
