Abstract

In the present study, the effect of broken channels on the NeuLAND performance was studied by looking at the efficiency of the Multiplicity Predictions and the inv. mass spectrum. First, a Stochastic Shut-Off was studied with neutron energies of 200, 600 and 1000 MeV. The Stochastic Shut-Off Scenario was studied by turning off a percentage of channels, which were chosen randomly for each single event. Then, a Worst-Case Scenario was proposed based on the number of the first neutron hits in a single channel with neutron energies of 600 and 1000 MeV. For the Worst-Case Scenario the same module(s), consisting of eight detectors stacked next to each other, was (were) turned off throughout the whole simulation. All simulations were done with twelve double planes. In order to assess the importance of the most crucial channels a comparison was made between the Stochastic Shut-Off and Worst-Case Scenario based on the inv. mass spectrum of events with a multiplicity of two and neutron energies of 1000 MeV.
