Simulations for the ASY-EOS II experiment — •Leandro Milhomens da Fonseca^1,3 and Igor Gašparić^2,3 for the R3B collaboration — ¹Technische Universität Darmstadt, Fachbereich Physik, Institut für Kernphysik, 64289 Darmstadt, Germany — ²Ruđer Bošković Institute, 10000 Zagreb, Croatia — ³GSI Helmholtzzentrum für Schwerionenforschung, 64291 Darmstadt, Germany

The ASY-EOS II experiment aims to place new and more stringent constraints on the density dependence of the symmetry energy at supra-saturation densities. The system proposed for the study is Au+Au at 250, 400, 600 and 1000 AMeV, which can only be performed nowadays at the GSI/FAIR facilities. The experiment is based on the NeuLAND detector to measure neutrons, protons and light-charged clusters emitted from mid-rapidity. To discriminate between neutrons and charged particles, it is the intention to use a VETO detector in front of the NeuLAND detector. It is a proposal to use a double plane of the R3B TOFD detector in front of the NeuLAND due to its ability to detect charged particles efficiently and let neutrons pass through without leaving any signal. As a proof of concept for this apparatus, this work aims to show simulations performed to determine detection efficiencies for the particles of interest and to assess the possibility of distinguishing the differently charged light particles coming from the reaction. This project was supported by the BMBF project No. 05P21RDFN2, and the GSI-TU Darmstadt cooperation.
