A fully active fine grained detector with three readout views

Abstract

This paper describes a novel idea of a fine-grained fully-active plastic scintillator detector made of many optically independent $1\times 1\times 1{\text{cm}}^3$ cubes with readout on three orthogonal projections by wavelength shifting fibers. The original purpose of this detector is to serve as an active neutrino target for the detection, measurement and identification of the final state particles down to a few tenths MeV kinetic energies. The three readout views as well as the fine granularity ensure powerful localization and measurement of the deposited energy combined with good timing properties and isotropic acceptance. The possible application as a new active target for the T2K near detector, initial simulation studies and R&D test results are reported.
