Upgraded readout electronics for the Neutron dEtector with Xn Tracking (NEXT) array

ORAL

Abstract

The advent of the new generation of radioactive ion beam facilities will enable studies of very neutron-rich nuclei near the drip line. In these regions, beta-delayed neutron emission becomes a dominant decay channel, and neutron spectroscopy is a powerful tool to elucidate the nuclear structure. The Neutron dEtector with Xn Tracking (NEXT) array has been developed for more precise time-of-flight measurements of neutrons [1]. A single NEXT module is composed of thin plastic scintillator bars and position-sensitive photomultipliers, and this design enables the localization of neutron interaction points for better energy resolution.

Since the initial design phases of NEXT prototypes [1], the readout electronics have been continuously upgraded, aiming at the full implementation of the NEXT array, which requires dedicated high-density triggering and readout schemes. Along with details on the upgrade, results from proof-of-principle measurements using the new electronics will be presented.
