A fully active fine grained detector with three readout views

Understand

This paper describes a novel idea of a fine-grained fully-active plastic scintillator detector made of many optically independent $1\times1\times1~\text{cm}^3$ 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.
