|Abstract:||In the present investigation the performance of digital data acquisition (DA) and analogue data acquisition (AA) systems are compared in neutron-induced fission experiments. The DA results are practically identical to the AA results in terms of angular-, energy- and mass resolution, and both compare very well with literature data. However, major advantages were found with the digital techniques. DA allows for a very effcient alpha-particle pile-up correction. This is important when considering the accurate measurement of fission-fragment characteristics of highly alpha-active actinide isotopes relevant for the safe operation of generation IV reactors and the successful reduction of long-lived radioactive nuclear waste. In case of a strong alpha-emitter, when applying the alpha-particle pile-up correction, the peak-to-valley ratio of the energy distribution was improved. In addition, DA offers a very exible expanded off-line analysis and reduces the number of electronic-modules drastically, leading to an increased stability against electronic drifts when long measurement times are required.|
