文摘

The ALICE Transition Radiation Detector (TRD) is equipped with 750m² total area of gas chambers with radiators for particle tracking and electron identification above 1GeV/c, divided in 540 modules organized in 18 sectors and 6 layers, in a barrel geometry between 2.9 and 3.7m from the beam axis. The TRD will also serve as a trigger on high-p_te⁺e⁻ pairs in order to reduce the collision rate to the readout event rate, by increasing the statistics on rare signals such J/ψ and . In this paper the ALICE TRD will be briefly introduced.
