An event display for the Transition Radiation Detector in ALICE

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...

Event by event physics in ALICE

Fluctuations of thermodynamic quantities are fundamental for the study of the QGP phase transition. The ALICE experiment is well suited for precise event-by-event measurements of various quantities. In this article, we review the capabilities of ALICE to study the fluctuations of several key observables such as the net charge, the temperature, and the particle ratios. Among the observables rela...
