    A Digital Front-End Electronics for the Neutron Detector NEDA
    (IEEE, 2014) Egea, F. J.; Houarner, C.; Boujrad, A.; Gonzalez, V.; Tripon, M.; Jastrzab, M.; Bourgault, P.
    This paper presents the design of the NEDA frontend electronics, a first attempt to involve the use of digital electronics in large neutron detector arrays. Among the electronic modules taking part, we emphasize on the front-end analog processing, the digitalization, digital pre-processing, communications firmware, as well as the integration of the Global Trigger and Synchronization system. The NEDA array will be available for measurements in 2015.

    Artificial neural networks for neutron/? discrimination in the neutron detectors of NEDA
    (Elsevier, 2021) Fabian, X.; Baulieu, G.; Ducroux, L.; Stezowski, O.; Boujrad, A.; Clement, E.; Coudert, S.
    Three different Artificial Neural Network architectures have been applied to perform neutron/gamma discrimination in NEDA based on waveform and time-of-flight information. Using the coincident gamma-rays from AGATA, we have been able to measure and compare on real data the performances of the Artificial Neural Networks as classifiers. While the general performances are quite similar for the data set we used, differences, in particular related to the computing times, have been highlighted. One of the Artificial Neural Network architecture has also been found more robust to time misalignment of the waveforms. Such a feature is of great interest for online processing of waveforms.

    Digital Front-End Electronics for the Neutron Detector NEDA
    (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2015) Egea Canet, F. J.; Houarner, C.; Boujrad, A.; Gonzalez, V.; Tripon, M.; Jastrzab, M.; Bourgault, P.
    This paper presents the design of the NEDA (Neutron Detector Array) electronics, a first attempt to involve the use of digital electronics in large neutron detector arrays. Starting from the front-end modules attached to the PMTs (PhotoMultiplier Tubes) and ending up with the data processing workstations, a comprehensive electronic system capable of dealing with the acquisition and pre-processing of the neutron array is detailed. Among the electronic modules required, we emphasize the front-end analog processing, the digitalization, digital pre-processing and communications firmware, as well as the integration of the GTS (Global Trigger and Synchronization) system, already used successfully in AGATA (Advanced Gamma Tracking Array). The NEDA array will be available for measurements in 2016.
