Simulations for an MRPC-based solution for the NeuLAND detector at FAIR — •Zoltán Elekes¹, Daniel Bemmerer¹, Mathias Kempe¹, Marko Röder², Manfred Sobiella¹, Daniel Stach¹, Andreas Wagner¹, Dmitry Yakorev¹, and Kai Zuber² — ¹Forschungszentrum Dresden-Rossendorf (FZD), Dresden — ²TU Dresden

The NeuLAND detector at the R³B experiment at the future FAIR facility in Darmstadt aims to detect fast neutrons (0.2-1.0 GeV) with high time and spatial resolutions (σ_t<100 ps, σ_x,y,z<1 cm). The multigap resistive plate chamber (MRPC) based prototypes developed so far and a full MRPC-based NeuLAND have been modeled in the R³BRoot simulation framework. The test-beam data obtained with the single-electron mode of the ELBE 40 MeV electron accelerator have been successfully reproduced in the simulation. The predicted response of the full-size NeuLAND for high-energy neutrons will be discussed. Namely, the quality of the position and TOF determination important for momentum reconstruction will be detailed. Furthermore, a key feature, i.e., the capability for multineutron recognition will also be presented. — Supported by BMBF (06DR9058I) and GSI FuE (DR-GROS and DR-ZUBE).
