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...
متن کاملEUROPEAN 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...
متن کاملSupervised algorithms for particle classification by a transition radiation detector
Support Vector Machines (SVM) provide an interesting computational paradigm for the classification of data from high energy physics and particle astrophysics experiments. In this study the classification power of support vector machines is compared with those from standard supervised algorithms, i.e. likelihood ratio (LR) and artificial neural networks (ANN), using test beam data from the trans...
متن کاملTransition 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...
متن کاملCharged particle identification in the ALICE experiment
A key feature of the ALICE experiment will be the capability to identify the charged particles in the full range of momentum thus allowing to investigate the properties of the quark-gluon plasma during its dynamical evolution toward the freeze-out phase when the re-hadronization occurs. Low momentum hadron identification will be achieved via measurements of energy loss in the silicon layers of ...
