“…Experiments with several calorimeters (e.g., [23]) have revealed that the hadronic energy resolution data are well described by a linear sum of a stochastic and constant term: which is, in the energy range covered by the current generation of test beams, i.e. up to 400 GeV, not distinguishable from Equation 3, albeit that the stochastic parameters differ (c 1 > a 1 ).…”

In the past 20 years, dual-readout calorimetry has emerged as a technique for measuring the properties of high-energy hadrons and hadron jets that offers considerable advantages compared with the instruments that are currently used for this purpose in experiments at the high-energy frontier. In this paper, we review the status of this experimental technique and the challenges faced for its further development Contents

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

“…In ATLAS, calorimeters cover the pseudorapidity region |η| < 4.9. 1 TileCal is a sampling calorimeter using plastic scintillator as the active material and lowcarbon steel (primarily iron) as the absorber. The tiles are placed in the iron structure in the η=0 plane, radially staggered in depth (see figure 1).…”

The Tile Calorimeter, covering the central region of the ATLAS experiment up to pseudorapidities of ±1.7, is a sampling device built with scintillating tiles that alternate with iron plates. The light is collected in wavelength shifting (WLS) fibers and is read out with photomultipliers. In the characteristic geometry of this calorimeter the tiles lie in planes perpendicular to the beams, resulting in a very simple and modular mechanical and optical layout. This paper focuses on the procedures applied in the optical instrumentation of the calorimeter, which involved the assembly of about 460,000 scintillator tiles and 550,000 WLS fibers. The outcome is a hadronic calorimeter that meets the ATLAS performance requirements, as shown in this paper.
