NEDA (NEutron Detector Array) is an instrument for detection of neutrons in the energy range from a few 100 keV to more than 10 MeV. It consists of a number of hexagonal liquid scintillator detectors with 5 inch photomultiplier tubes. The detectors can be mounted in a closely packed array and combined with other detectors, for example AGATA. The signals produced by the NEDA detectors are read out and processed by digital electronics. Pulse-shape discrimination combined with time-of-flight discrimination of neutrons and gamma rays can be performed online in real-time as well as offline.
