Physics with the ALICE Transition Radiation Detector

Calibration of the ALICE Transition Radiation Detector

The Transition Radiation Detector (TRD) belongs to the central barrel detectors of the ALICE experiment at the LHC at CERN. It is composed of 540 large area drift chambers, with a total of 1181952 readout pads (1728 or 2304 per chamber). To ensure the optimal performance of the detector, designed for electron/pion identification and charged particle tracking, including triggering for high-pt el...

EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH European Laboratory for Particle Physics The ALICE Transition Radiation Detector

In this talk an overview of the ALICE TRDis presented. The ALICE TRD consists of 540 individual detector modules with a total of 1.2 million readout channels. It allows electron identi cation above a momentum of 1 GeV/c and is capable of providing a very fast and eÆcient trigger on electrons with large transverse momentum pt. It will operate in a very high multiplicity environment. The rapidity...

Transition Radiation Spectroscopy with Prototypes of the ALICE TRD

Measurements of TR yield and spectra for a large variety of regular radiator configurations have been presented by different authors. In general, data confirm the theoretical predictions [1], although total TR yield and dependence on the momentum of the emitting particle are not always reproduced [2][3]. The ALICE Transition Radiation Detector (TRD) consists of 540 drift chambers with mixed fib...

Operational experience with the ALICE Pixel Detector

The ALICE Silicon Pixel Detector (SPD) constitutes the innermost detector of the ALICE experiment, which is the LHC experiment dedicated to the investigation of strongly interacting matter in heavy-ion collisions. The SPD consists of ∼10 million pixels organized in two layers at radii of 39 mm and 76 mm that cover a pseudorapidity range of |η |< 2 and |η |< 1.4, respectively. It provides the po...
