The detection of rare events close to the proton dripline involve the utilization of high-efficient neutron detectors with excellent neutron-gamma discrimination (NGD) performance. Even though in the literature, several off-line algorithms focus on the maximization of the NGD accuracy, our aim is to look for an on-line efficient implementation capable to discard a majority of the gamma-rays, therefore allowing the system to work to counting rates up to 50 kHz, optimizing hence the overall electronics infrastructure in terms of data throughput. In this paper we analyze two of the most widespread techniques for NGD based on PSA, i.e. the charge-comparison method (CC) and the zero crossover (ZCO). Then, based on the NGD performance and FPGA resource utilization, we select one to be implemented in an FPGA. Finally we present the preliminary results obtained up to now.

This work describes new electronics for the EX-OGAM2 (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).

18th IEEE-NPSS Real Time Conference (RT) on Computing Applications in Nuclear and Plasma Sciences -- JUN 11-15, 2012 -- Berkeley, CA, WOS: 000325827700015, This work describes new electronics for the EX-OGAM2 (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). The PSA is of paramount importance for the NEDA to discriminate between neutrons and gamma-ray signals. Both high resolution and high speed parameters are often difficult to achieve in a single electronic unit. These constraints, together with the need to build new digitizing electronics to improve performance and flexibility of signal analysis in nuclear physics experiments, led to the development a new FADC mezzanine card. In this work, the design and development are described, including the characterization procedure and the preliminary measurement results., Generalitat Valenciana, Spain [PROMETEO/2010/101]; Swedish Research Council; Scientific and Technological Research Council of Turkey (TUBITAK); INFN, Italy; Spanish MINECO [AIC-D-2011-0746, FPA2011-29854, FPA2012-33560], This work was supported by the Generalitat Valenciana, Spain, under Grant PROMETEO/2010/101, the Swedish Research Council, and the Scientific and Technological Research Council of Turkey (TUBITAK).
