Conclusions

We have investigated the simulated response of the RPC and DTBX trigger systems in the barrel region to single muons in the region between 5 and 100 GeV/c. We find

• acceptable reconstruction efficiencies for both systems
• acceptable resolutions in and , which still can be improved in the DTBX system by more fine-graining and inclusion of the third superlayer in the algorithm
• inefficiencies due to cracks and construction properties of the detectors. Therefore the efficiency curves will be different
• different behaviour of the systems for fixed trigger thresholds due to design logic in the assignment and resolution
• a Global Muon Trigger logic can make use of these differences and gives an overall higher efficiency and also a smoothing effect in the less efficient regions of and
• ghost tracks, especially from the DTBX system, have to be eliminated by ``quality'' criteria expressed via quality bits in the trigger logic
• up to 4 muons can be reconstructed without additional loss in efficiency compared to single muons
• a careful tuning of the trigger-thresholds is required to avoid too high trigger rates

We want to note that all our results depend crucially on the implementation of the Muon Track Finder which was available for us just as a preliminary version.
