Construction and test of a 2 m long MRPC-based prototype for the NeuLAND detector at FAIR — •Dmitry Yakorev1, Daniel Bemmerer1, Mircea Ciobanu2, Zoltán Elekes1, Mathias Kempe1, Marko Röder3, Manfred Sobiella1, Daniel Stach1, Andreas Wagner1, and Kai Zuber3 — 1Forschungszentrum Dresden-Rossendorf (FZD), Dresden — 2GSI, Darmstadt — 3TU 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 (σt<100 ps, σx,y,z<1 cm). The final detector should cover an area of 2 m x 2 m.
Based on the previous experience with 40 cm long prototypes, recently a 2 m long prototype of an multigap resistive plate chamber (MRPC) based solution for NeuLAND has been designed and constructed at FZD. Its efficiency for minimum ionizing particles and the time resolution have been tested using the single-electron mode of operation of the ELBE 40 MeV electron accelerator. The salient features of this full-size prototype, the results of the in-beam tests, and future work will be discussed. — Supported by BMBF (06DR9058I) and GSI FuE (DR-GROS and DR-ZUBE).
