TL;DR: In this paper, test-beam studies of the ATLAS Transition Radiation Tracker (TRT) straw tube performance in terms of electron-pion separation using a time-over-threshold method are described.
Abstract: Test-beam studies of the ATLAS Transition Radiation Tracker (TRT) straw tube performance in terms of electron–pion separation using a time-over-threshold method are described The test-beam data are compared with Monte Carlo simulations of charged particles passing through the straw tubes of the TRT For energies below 10 GeV , the time-over-threshold method combined with the standard transition-radiation cluster-counting technique significantly improves the electron–pion separation in the TRT The use of the time-over-threshold information also provides some kaon–pion separation, thereby significantly enhancing the B-physics capabilities of the ATLAS detector

TL;DR: In this article, a beam-directing device (BDD) was used to direct the X-ray beam in a chosen direction within some solid angle and supplying an accurate angular measurement system.
Abstract: The end-cap Transition Radiation Tracker (TRT), consisting of 36 modules (wheels), is being constructed as a part of the ATLAS Inner Detector at the CERN LHC. This paper describes a method for determining the wire positions inside the straw proportional tubes (SPT), which are the basic building blocks of the ATLAS TRT, with an accuracy of better than 10 μm . The procedure involves moving a narrow monochromatic X-ray beam across the straw and measuring the counting rate as a function of the position of the X-ray beam in the straw. To achieve this goal, a Beam Directing Device (BDD), providing the possibility to direct the X-ray beam in a chosen direction within some solid angle and supplying an accurate angular measurement system, has been constructed. The results of the wire position measurements performed using this BDD on a full-scale mechanical prototype end-cap wheel of the TRT are presented in this paper.

TL;DR: In this paper, the registration results for the registration of the isolated 10 GeV/c pions and electrons in the straw TRD detector are presented, and different techniques of signal processing have been used: cluster counting (N method), total energy deposition (Q method), and two-dimensional spectra (Q, N method).
Abstract: Calculation results for the registration of the isolated 10 GeV/ c pions and electrons in the straw TRD detector are presented. Different techniques of signal processing have been used: cluster counting ( N method), total energy deposition ( Q method) and two-dimensional spectra ( Q , N method). Calculations were carried out for different modifications of the detector module.
