An analog hadron calorimeter (AHCAL) prototype of 5.3 nuclear interaction lengths thickness has been constructed by members the CALICE Collaboration. The AHCAL consists a 38-layer sandwich structure steel plates and highly-segmented scintillator tiles that are read out wavelength-shifting fibers coupled to SiPMs. signal is amplified shaped with custom-designed ASIC. A calibration/monitoring system based on LED light was developed monitor SiPM gain measure full response curve in order correct...
The studies presented in this paper provide a first experimental test of the Particle Flow Algorithm (PFA) concept using data recorded high granularity calorimeters. Pairs overlaid pion showers from CALICE 2007 beam are reconstructed by PandoraPFA program developed to implement PFA for future lepton collider. Recovery neutral hadron's energy vicinity charged hadron is studied. impact two overlapping on resolution investigated. dependence confusion error distance between 10 GeV and derived...
The energy resolution of a highly granular 1 m3 analogue scintillator-steel hadronic calorimeter is studied using charged pions with energies from 10 GeV to 80 at the CERN SPS. for single hadrons determined be approximately 58%/sqrt(E/GeV}. This improved 45%/sqrt(E/GeV) software compensation techniques. These techniques take advantage event-by-event information about substructure showers which provided by imaging capabilities calorimeter. reconstruction either corrections based on local...
The ATLAS detector has been designed for operation at the Large Hadron Collider CERN. includes electromagnetic and hadronic liquid argon calorimeters, with almost 200,000 channels of data that must be sampled LHC bunch crossing frequency 40 MHz. calorimeter electronics calibration readout are performed by custom developed specifically these purposes.

The CALICE collaboration is studying the design of high performance electromagnetic and hadronic calorimeters for future International Linear Collider detectors. For calorimeter, one option a highly granular sampling calorimeter with steel as absorber scintillator layers active material. High granularity obtained by segmenting into small tiles individually read out via silicon photo-multipliers (SiPM). A prototype has been built, consisting thirty-eight sensitive layers, segmented about...
A prototype silicon-tungsten electromagnetic calorimeter for an ILC detector was tested in 2007 at the CERN SPS test beam. Data were collected with electron and hadron beams energy range 8 to 80 GeV. The analysis described here focuses on interactions of pions calorimeter. One main objectives CALICE program is validate Monte Carlo tools available design a full-sized detector.
