In this paper it is shown that a measurement of the relative luminosity changes at LHC may be obtained by analysing currents drawn from high voltage power supplies electromagnetic section forward calorimeter ATLAS detector. The method was verified with reproduction small using proton beams known beam energies and variable intensities U-70 accelerator IHEP in Protvino, Russia. experimental setup data taking during test run April 2008 are described detail. A comparison measured reference...
Three ATLAS calorimeters in the region of forward crack at |η| = 3.2 nominal setup and a typical section two barrel 0.45 have been exposed to combined beam tests with single electrons pions. Detailed shower shape studies pions comparisons various Geant4 based simulations utilizing different physics lists are presented for endcap test. The local hadron calibration approach as used full Atlas has applied test data. An extension it using layer correlations tested Both methods utilize modular...
The validation of GEANT4 physics models is done by comparing experimental data from beam tests modules the ATLAS hadronic end-cap calorimeter with based simulations. Various lists for simulation showers are evaluated. We present results studies performance parameters (like energy resolution and shower shapes) as well investigations influence Birks' law cuts on time development showers.
The Geant4 simulation toolkit is currently adopted by many particle physics experiments, including those at the Large Hadron Collider and ones proposed for future lepton hadron colliders. In present era of precision tests Standard Model increasingly detailed detectors colliders scenario, plays a key role. It required to remain reliable stable detector simulations same time undergo major improvements in both accuracy computational performance. Calorimeter beam involve various particles...
Validation of GEANT4 hadronic physics models is carried out by comparing experimental data from beam tests modules the ATLAS end‐cap calorimeters with based simulations. Two lists (LHEP and QGSP) for simulation showers are evaluated. Calorimeter performance parameters like energy resolution response charged pions shapes studied. Comparison GEANT3 predictions done as well.
