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. © 1963-2012 IEEE.

The present paper aims to present the final design and results of the FADC Mezzanine for EXOGAM and NEDA detectors, focusing on the resolution performance. Finally, the conclusion shows how a common digitizing device has been integrated in an experimental environment involving low-noise and fast sampling rates. Not only the integration fulfilled the expected specifications on both systems, but also, it shows how a study of synergy between detectors has led to a reduction of resources and time by applying a common strategy. © 2014 IEEE.

This work describes new electronics for the EXOGAM2 (HP-Ge detector array) and NEDA (BC501A-based neutron detector array). A new digitizing card with high resolution has been designed for gamma-ray and neutron spectroscopy experiments. The higher bandwidth requirement of the NEDA signals, together with the necessity for accuracy, require a high sampling rate in order to preserve the shape for real-time Pulse Shape Analysis (PSA). © 2013 IEEE.
