Description
The Joint Research Activity 1 of EFNUDAT was dealing with the development of novel data acquisition techniques for nuclear data measurements based on wave-form digitization. JRC-IRMM was involved in the development of fast digital data acquisition systems as well as digital signal processing (DSP) routines for off-line treatment of the sampled signal wave-forms.
Two different digital data acquisition systems (DDA) are presently in use at JRC-IRMM. One is dedicated to the measurement of fission fragments as well as prompt fission gamma-rays and neutrons. The second DDA is used for investigating elastic scattering processes.
In the frame of the investigation of neutron-induced fission of 234U as a function of incident neutron energy both analogue and digital data acquisition systems are being compared, showing the beneficial application of DDA in terms of e. g. a highly efficient pile-up correction.
A Java based TCD-1.0 system is also in use for the measurement of elastic scattering angular distributions at the GELINA facility using different detector systems (e.g. the GAINS array as well as Ge-based elastic scattering detector with a 10B converter disk).
A Java based TCD-1.0 system is also in use for the measurement of elastic scattering angular distributions at the GELINA facility using different detector systems (e.g. the GAINS array as well as an array of 8 Li-glass and 8 liquid scintillation detectors).
The superiority of DDA in conjunction with the application of dedicated DSP routines will be discussed and a comparison with the traditional analogue technique presented.
