摘要：

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 efficient 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 significantly improved In addition DA offers a very flexible 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 (C) 2010 Elsevier B V All rights reserved
