Straw tubes are known as excellent tools for particle tracking. A multilayer, densely packed ensemble of about 5000 straw tubes - so called Straw Tube Trackers (STT) is considered as an option for the central tracker of the future PANDA@FAIR experiment. Simulations indicate that the energy loss of particles traversing several layers of straw tubes can in addition result in a decisive contribution to particle discrimination in the momentum range up to 1.5 GeV/c. Experimental investigation of the energy resolution in prototype of the PANDA-type STT have been undertaken in Research Center Jülich (Germany). The experimental setup, readout electronics, method of data treatment and the encouraging results are presented.

Abstract
Straw tubes are known as excellent tools for particle tracking. A multilayer, densely packed ensemble of about 5000 straw tubes - so called Straw Tube Trackers (STT) is considered as an option for the central tracker of the future PANDA@FAIR experiment. Simulations indicate that the energy loss of particles traversing several layers of straw tubes can in addition result in a decisive contribution to particle discrimination in the momentum range up to 1.5 GeV/c. Experimental investigation of the energy resolution in prototype of the PANDA-type STT have been undertaken in Research Center Jülich (Germany). The experimental setup, readout electronics, method of data treatment and the encouraging results are presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
