“…This prototype has been tested with high energy electron and pion beams at the CERN Super Proton Synchrotron (SPS) together with a LAr hadronic calorimeter prototype which also had an Accordion geometry [6]. The main points to be investigated in the electromagnetic part were the capability of maintaining the energy resolution at the level of 10%= p E(GeV)…”

A 2 metre long prototype of a lead-liquid argon electromagnetic calorimeter with accordionshaped electrodes, conceived as a sector of the barrel calorimeter of the future ATLAS experiment at the LHC, has been tested with electron and pion beams in the energy range 10 to 287 GeV. A sampling term of 10%= p E(GeV) was obtained for electrons in the rapidity range 0 < < 1, while the constant term measured over an area of about 1 m 2 is 0.69%. With a cell size of 2.7 cm the position resolution is about 4 mm= p E(GeV).

“…6 compares our values of the ðe=pÞ LAr ratio to the ones obtained in Refs. [8][9][10] using a weighting method. The results are in good agreement below 100 GeV but disagree above this energy because the weighting method leads to a distortion of the ðe=pÞ LAr ratios.…”

This paper discusses hadron energy reconstruction for the ATLAS barrel prototype combined calorimeter (consisting of a lead-liquid argon electromagnetic part and an iron-scintillator hadronic part) in the framework of the nonparametrical method. The non-parametrical method utilizes only the known e=h ratios and the electron calibration constants and does not require the determination of any parameters by a minimization technique. Thus, this technique lends itself to an easy use in a first level trigger. The reconstructed mean values of the hadron energies are within 71% of the true values and the fractional energy resolution is ½ð5873Þ%= ffiffiffi ffi E p þ ð2:570:3Þ%"ð1:770:2Þ=E: The value of the e=h ratio obtained for the electromagnetic compartment of the combined calorimeter is 1:7470:04 and agrees with the prediction that e=h > 1:66 for this electromagnetic calorimeter. Results of a study of the longitudinal hadronic shower development are also presented. The data have been taken in the H8 beam line of the CERN SPS using pions of energies from 10 to

The first combined test of an electromagnetic liquid argon accordion calorimeter and a hadronic scintillating-tile calorimeter was carried out at the CERN SPS. These devices are prototypes of the barrel calorimeter of the future ATLAS experiment at the LHC. The energy resolution of pions in the energy range from 20 to 300 GeV at an incident angle of about 11 is well-described by the expression =E = 46:5 6:0 = p E + 1 : 2 0 : 3 3:2 0:4 GeV=E. Shower profiles, shower leakage, and the angular resolution of hadronic showers were also studied.
