Prototyping and design for a time-of-flight detector for 1 GeV neutrons at R3B/FAIR

Bemmerer, D.

At the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, uniquely intensive beams of radioactive ions will become available, enabling many experiments of astrophysical relevance. The Reactions with Relativistic Radioactive Beams (R3B) setup at FAIR will study reactions of such projectiles at energies up to 1 GeV/A. As part of R3B, the planned NeuLAND (New Large Area Neutron Detector) time-of-flight detector shall detect emitted neutrons with a time resolution of sigma < 100 ps and efficiency >90%. Two possible solutions are currently under study for NeuLAND: a pure scintillator concept and a design based on passive converters and multigap resistive plate chambers (MRPC's). The poster will outline the design work on the MRPC-based solution. The measured properties of a 200 cm * 50 cm large MRPC-based neutron detector prototype will be shown, the first device of such a size with thick passive converters inside the MRPC structure.
