“…It simulates the production of TR photons in radiators and their absorption in materials and in the working gas based on the approaches described in [8]. Ionization losses (dE/dx) in the detectors are simulated using PAI model [9]. In order to obtain a good agreement with measurements, some apparatus effects which have essential influence on the observed data must be taken into account.…”

Studying of hadron production in forward direction at the LHC energy has a great interest both for understanding of the fundamental QCD processes and also in applied areas such as the description of ultra-high energy cosmic particle interactions. The energies of secondary hadrons in such studies almost reach the maximum energy available at the LHC of ∼6 TeV, which corresponds to a Lorentz γ-factor up to 10 4 and above. The only effective technique able to identify particles in this range is based on the transition radiation detectors (TRD). Prototypes of such kind of detector were built and tested at the CERN SPS accelerator. Some experimental results obtained in these tests are briefly presented here and compared with Monte Carlo (MC) simulations. MC model demonstrates a good agreement with the experiment. On this basis a concept of a full-scale TRD optimized for the hadron identification in the TeV energy region is proposed. Different particle identification techniques were considered and examined. The expected detector performance to reconstruct secondary hadrons produced in forward direction at the LHC is presented.

“…It includes detailed models to describe the energy deposition in the straws, transition-radiation creation and absorption and the response of the front-end electronics [12]. The energy loss for each charged particle crossing the ionisation gas is calculated using the Photo-Absorption Ionisation (PAI) model [13]. This ionisation is deposited over a small (typically $ 50 per cm for minimumionising particles, while $ 70 per cm for particles at the Fermi plateau) number of primary ionisation centres along the path length.…”

Test-beam studies of the ATLAS Transition Radiation Tracker (TRT) straw tube performance in terms of electronpion 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-overthreshold 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. #

In order to improve the accordance between measured and calculated energy loss distributions a new tuning method is suggested. The idea is that the oscillator strength function or, equivalently, the dielectric function of the specific medium used in the detector can be extracted from a deconvoluted well measured dE=dx spectrum. This procedure involves rather delicate numerical problems, which will be discussed in detail. The method is in particular suitable for detectors with thin layered sampling (xP < 1 cm) where traditional methods tend to fail due to the difficulties of correcting for detector inefficiencies and smearing. This is illustrated by testing the method on data from a thin layered Time Projection Chamber, TPC.
