The 2D neutron emissivity profile is measured at JET by a set of NE213 liquid organic scintillators, located in two fan-shaped arrays of collimators with 10 horizontal and 9 vertical lines of sight. As the detectors are sensitive to neutron and gamma rays, pulse shape analysis is required for neutron/gamma discrimination. A digital architecture data-handling data acquisition and processing for the entire diagnostic has been developed by ENEA-Frascati and installed at JET during the 2009 campaign as a replacement of the existing analogue electronics. This paper describes the performances of the digital system and the first experimental results in the JET C27b campaign. © 2011 EURATOM Published by Elsevier B.V. All rights reserved.
