AB The focus of this report is the neutron detection for the ALADiN-LAND setup at GSI/FAIR. Especially the evaluation of algorithms for reconstructing neutrons inside the LAND-detector, based on simulated data using GEANT3/GEANT4. The algorithm used since 1990 has been compared with a new experimental probabilistic algorithm. The algorithms have also been tested with the next generation neutron detector concepts (NeuLAND).
For LAND both algorithms perform similarly, with the main difference that the new algorithm is much slower. The performance of reconstructing the four vector for single incoming neutrons is reasonably good, but decrease with increased number of incoming neutrons. To increase the performance for larger number of incoming neutrons, modification of the existing algorithms are needed.
