Digitisation Techniques Applied in Nuclear Measurements

Digitisation techniques are being rapidly adopted to nuclear measurements due to large progress made in computing performance. Waveform digitisers are able to record the complete detector output signal with a high dynamic range. This method has obvious advantages compared to the traditional analogue technique, where separate electronic units are applied for selection and storage of the information: Full information contained in the output signal of a detector is recorded and makes possible to apply different signal processing algorithms during data analysis to focus on different aspects of the given experiment using the same data set repeatedly. The choice is limited only by the imagination of the experimentalist. It is also possible to increase the counting rate while maintaining successful particle discrimination still being able to fully determine the physical properties of events separated by a few hundreds of nanoseconds. The rapid increase in computer power and in data storage capacity stimulated the use of waveform digitizers as a new technique for nuclear experiments. The apparent advantages have been demonstrated in recent feasibility studies. It has been shown, that this technique improves the quality of particle identification, the dynamic range as well as the electronic stability during the experiment.
