“…The total energy was calculated from the following relation: E tot = ( E ps + E 1 + E 2 + E 3 ), where E ps , E 1 , E 2 , E 3 refer to the signals collected in the presampler and the three calorimeter radial compartments, , and are weights introduced to minimize the width of the energy distribution and is an overall calibration coe cient. Standard position-dependent energy corrections were applied to the calorimeter in order to correct for the shower containment i n and the modulation of the transverse LAr thickness in [1]. Figure 6 shows the energy resolutions obtained with the copper and the optical links.…”

The electromagnetic calorimeter of the ATLAS experiment at the CERN Large Hadron Collider (LHC) will be of the accordion liquid argon (LAr) type. To a c hieve su cient energy resolution it is necessary to correct for the energy loss upstream of the calorimeter. For this purpose a separate presampler detector, providing a shower sampling in a thin LAr layer (11 mm in depth) before the calorimeter, was developed by the ATLAS collaboration and tested at CERN in September 95. The combined response of this detector and a calorimeter prototy p e t o m uons and electrons is presented.

A separate liquid argon preshower detector consisting of two l a y ers featuring a ne granularity of 2.5 10 3 was studied by the RD3 collaboration. A prototype covering approximately 0.8 in pseudo-rapidity and 9 degrees in azimuth was built and tested at CERN in July 94. CMOS and GaAs VLSI preampli ers were designed and tested for this occasion. The combined response of this detector and an accordion electromagnetic calorimeter prototype to muons, electrons and photons is presented. For minimum ionizing tracks a signal-to-noise ratio of 4.5 per preshower layer was measured. Above 150 GeV the space resolution for electrons is better than 250 m in both directions. The precision on the electromagnetic shower direction, determined together with the calorimeter, is better than 4 mrad above 50 GeV. It is concluded that the preshower detector would adequately ful l its role for future operation at CERN Large Hadron Collider.
