The increase of the light collection from scintillation strip with hole for WLS fiber using various types of fillers

The light collection of the extruded scintillator strip samples with WLS fibers placed in the longitudinal hole in the plates was measured. The holes were filled with various liquid fillers. Measurements were carried out under irradiation by cosmic muons. The method of pumping liquid filler with viscosity more than 10 Pa*s in the strip hole with WLS fiber inside was designed and successfully tested.

Hadronic Calibration of the ATLAS Liquid Argon End-Cap Calorimeter in the Pseudorapidity Region 1.6 < |eta| < 1.8 in Beam Tests

A full azimuthal phi-wedge of the ATLAS liquid argon end-cap calorimeter has been exposed to beams of electrons, muons and pions in the energy range 6 GeV <= E <= 200 GeV at the CERN SPS. The angular region studied corresponds to the ATLAS impact position around the pseudorapidity interval 1.6 < |eta| < 1.8. The beam test set-up is described. A detailed study of the performance is given as well as the related intercalibration constants obtained. Following the ATLAS hadronic calibration proposal, a first study of the hadron calibration using a weighting ansatz is presented. The results are compared to predictions from Monte Carlo simulations, based on GEANT 3 and GEANT 4 models.
