The HADES Upgrade: first Results
During the year 2010 the HADES Upgrade project has been finalized and the spectrometer has been commissioned in three test beam times at the end of the year. The HADES upgrade program had the following main goals: (1) The installation of a new Resistive Plate Chamber (RPC) detector to increase the time resolution and granularity of the time-of-flight system at the lower polar angles (θ < 45). (...
متن کاملMeson Reconstruction in Pp Reactions at 2.2 Gev with Hades
The HADES spectrometer, which is described in more details in the contribution of Ref. 1, is a highly selective tool specially suited for the study of the high energy dielectron decay channels in nucleus-nucleus collisions around 1-2 A GeV, as well as in proton and pion induced reactions. In order to provide absolute measurements of invariant mass distributions a good knowledge of the dielectro...
متن کاملSimulation studies of the HADES first level trigger. PART I: Performance in heavy-ion induced reactions
The first level trigger of the HADES spectrometer is studied for the heavy-ion collision systems Au+Au and Ne+Ne. The trigger efficiency for central events is given in dependence of the imposed charged particle multiplicity condition. The timing properties of the trigger signal are described. The losses due to deadtime are specified. Finally, the first level trigger rate is reported. UCY–PHY–96...
متن کاملSimulation studies of the HADES first level trigger. PART II: Performance in hadron induced reactions
The HADES first level trigger is studied for the system p+Ni at a beam energy of 2 AGeV. The timing properties of the trigger signal are reported. The efficiency loss due to deadtime is specified. A trigger requirement of a time overlap window with the start detector is described. The trigger rates for different overlap windows are given.
