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 کاملA Large Area Transition Radiation Detector for theNOMAD
A Transition Radiation Detector to identify electrons at 90% ef-ciency with a rejection factor against pions of 10 3 on an area of 2:85 2:85 m 2 has been constructed for the NOMAD experiment. Each of its 9 modules includes a 315 plastic foil radiator and a detector plane of 176 vertical straw tubes lled with a xenon-methane gas mixture. Details of the design, construction and operation of the d...
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 کاملInterstrip Capacitance of a Prototype Stipixel Detector
We measured the inter-strip capacitance on a prototype DC-coupled "stripixel" detector (SPD) employing circular spirals with two methods, each of them employing a RC-chip to bias and read out the detectors. Both yielded the same value of Cint = 1.1 pF for a strip length of 1.4 mm, indicating the total inter-strip capacitance to be much larger than on ordinary silicon strip detectors (SSD).
متن کاملPhoton -counting Reticontm Detector
For applications in faint -object spectroscopy at the Mt. Hopkins Observatory, a photon counting detector has been built using a dual 936 Reticon diode array fibre -optically coupled to a high -gain image intensifier package. The electronic signal processing follows closely the design of Shectman; the diode array is scanned every millisecond, each frame is subtracted from the previous to minimi...
