The cell response of electrons entering the calorimeter modules exposed to the beam at incidence angle of 20 deg, normalized to beam energy, with one entry for each A-cell measured. The plot contains data at various energies ranging from 20 to 180 GeV. The mean value 1.050±0.003 pC/GeV defines the Tilecal EM scale factor. The RMS spread of (2.4±0.1)% is due to local variations in individual tile & tile/fiber responses as confirmed by special MC studies.

Pions

Pion response vs. energy of incident pions at |η|=0.35
- Top: measurements were taken with many calorimeter modules and the response of each is normalized to the mean response at the common energy of 180 GeV. Open squares represent Geant4.8.3 Monte Carlo simulations, with QGSP and Bertini intranuclear cascade models.
- Bottom: experimental data corrected for longitudinal and transverse energy leakage as derived from data taken in special 90 deg configuration and Geant4 MC simulation. The energy dependence is due to calorimeter non-compensation; the displayed fit uses Groom's parametrization of the non-EM component of hadronic showers with F_h = (E_beam/E_0) ^m-1

The Tilecal-standalone energy resolution for pions impinging on the calorimeter at |η|=0.35 (equivalent calorimeter depth 7.9λ), as a function of the beam energy. MC simulation results (Geant4.8.3 QGSP+Bertini models, shown with open squares) are in agreement with data (full circles). The electronic noise contribution is found to be negligible so only statistical and constant terms are used in the fit.
Note that in the ATLAS configuration the total calorimeter (EM LAr + Tilecal) depth is larger by about 30%, hence the longitudinal leakage is smaller and its contribution to the energy resolution degradation is smaller (see also next plot). The expected constant term for jet energy resolution in ATLAS is typically 2.6% ( CERN-OPEN-2008-020, page 306, Table 3)

The dependence of the energy resolution of Tilecal on the depths of the calorimeter for pions as measured in the 90deg testbeam configuration. The resolution is defined as σ/peak of a Gaussian fit to the distribution in the range -2σ to 2σ around the peak value. The resolution is normalized to the one at 10.9 λ. Vertical lines indicate the depth of TileCal (7.4λ) and full ATLAS calorimeter (9.7λ) at η = 0.

Comparison with Monte Carlo simulations

Visible energy in TileCal
Mean value of the energy released in TileCal by a pion beam at η=-0.35 of several energies. The mean is extracted with a 2 sigma Gaussian fit of the energy distribution. Experimental data and Monte Carlo simulations are calibrated to the electromagnetic scale using a sample of 20 GeV electrons. The exact beam composition is reproduced in the Monte Carlo samples.
Data obtained with TileCal standalone test-beam 2002 setup: a three layers stack with a prototype barrel module a production barrel module and two extended barrel modules on top.

Longitudinal shower shape
Fraction of the total energy released by a pion beam in each longitudinal sample of the Tile calorimeter. The first section (Sample A), of about 1.4 interaction length, samples the beginning of the shower development, the second (Sample BC) is the longest section (4λ) and contains the bulk of the hadronic shower. The last sample (Sample D) measures the energy in the tail of the shower.

The cell response of electrons entering the calorimeter modules exposed to the beam at incidence angle of 20 deg, normalized to beam energy, with one entry for each A-cell measured. The plot contains data at various energies ranging from 20 to 180 GeV. The mean value 1.050±0.003 pC/GeV defines the Tilecal EM scale factor. The RMS spread of (2.4±0.1)% is due to local variations in individual tile & tile/fiber responses as confirmed by special MC studies.

Noise in PMT#2 connected to cell A1 (LBC - Demonstrator).
Electronic noise RMS was evaluated for each channel of LBC using amplitude of the first sample.
Noise is about 0.75 counts for most of the channels.
N.B: In this part of the analysis true 12-bit ADC readout of new system was converted to 10 bits range, to be compatible with 10-bit readout in legacy system (i.e. actual signal in ADC counts is 4 times bigger).

Visible energy in TileCal
Mean value of the energy released in TileCal by a pion beam at η=-0.35 of several energies. The mean is extracted with a 2 sigma Gaussian fit of the energy distribution. Experimental data and Monte Carlo simulations are calibrated to the electromagnetic scale using a sample of 20 GeV electrons. The exact beam composition is reproduced in the Monte Carlo samples.
Data obtained with TileCal standalone test-beam 2002 setup: a three layers stack with a prototype barrel module a production barrel module and two extended barrel modules on top.

Longitudinal shower shape
Fraction of the total energy released by a pion beam in each longitudinal sample of the Tile calorimeter. The first section (Sample A), of about 1.4 interaction length, samples the beginning of the shower development, the second (Sample BC) is the longest section (4λ) and contains the bulk of the hadronic shower. The last sample (Sample D) measures the energy in the tail of the shower.
Data obtained with TileCal standalone test-beam 2002 setup: a three layers stack with a prototype barrel module a production barrel module and two extended barrel modules on top. Pions impinging at η=-0.35.

Lateral shower shape
Lateral profile of the hadronic shower from a pion beam in TileCal. Ecore is the energy released in the projective tower hit by the pion beam (0.1x0.1 in ΔηxΔφ). The energy in the volume around this tower measures the size of the shower halo (Ehalo).
Data obtained with TileCal standalone test-beam 2002 setup: a three layers stack with a prototype barrel module a production barrel module and two extended barrel modules on top. Pions impinging at η=-0.35.

Sampling fraction

Changed:
<
<
Reverse value of the sampling fraction (1/SF) as the function of pseudo-rapidity. The quantity is given by the ratio of beam energy over visible energy. The values are constant over a large -region. The increase of 1/SF at small can be qualitatively explained by the periodic iron/scintillator structure of the TileCal. In the simulation the energy deposited by particles in a cell at the EM scale in TileCal is calculated as the energy released in the scintillators multiplied by the factor determined at η=0.35 consistently with the EM scale used for the data obtained with electrons at Test Beams.

Determinations of ratio of the incident electron energy E over the simulated visible energy deposited in the cells 1/SF without and with the introduction of the U-shape in the Test Beams MC. The systematic error Δ_?imp corresponds to the uncertainty on the impact point of the electrons on the cell of about 20 mm in y at Test Beams. The diff erence of the values of 1/SF obtained using two diff erent methods Δ_?meth is smaller than 0.1%. The considered systematic errors do not a ffect the determinations of 1/SF without U-shape simulation.

Pions

Energy responses of positive pions with energies of 20, 50, 100 and 180 GeV incident on the ATLAS Tile Calorimeter with special (90 deg) test beam setup: three layers stack with a prototype barrel module a production barrel module and two extended barrel modules on top. Top: the black dots represent the data obtained during 2000-2003, and the other colored markers represent the MC simulation with several physics lists. Bottom: the ratio of Monte Carlo to data. The error bars are statistical only. Geant4 version 10.1 with the FTFP_BERT, FTFP_BERT_ATL, QGSP_BERT and QGSP_BIC physics lists is used for simulation. FTFP_BERT and FTFP_BERT_ATL can describe data better, mostly within 1%, while QGSP_BERT and QGSP_BIC give lower and higher energy responses separately, the overestimation and underestimation are more than 1%.

Electrons

The cell response of electrons entering the calorimeter modules exposed to the beam at incidence angle of 20 deg, normalized to beam energy, with one entry for each A-cell measured. The plot contains data at various energies ranging from 20 to 180 GeV. The mean value 1.050±0.003 pC/GeV defines the Tilecal EM scale factor. The RMS spread of (2.4±0.1)% is due to local variations in individual tile & tile/fiber responses as confirmed by special MC studies.

Example of the isolated muon signal as measured in the stand-alone calibration test beams of the calorimeter at η=0.35 in the whole tower (top) and in a cell of the last radial compartment (bottom). The EM scale is 1.05 pC/GeV. The signal is very well separated from the noise (shown by narrow peaks), the signal-to-noise ratio is ~44 (tower) and ~18 (last radial compartment) respectively. The last radial compartment can be used to tag muons inside jets. The response shown is associated with the full resolution data available at trigger level 2 and above.

The total calorimeter response to 180 GeV muons, normalized to the path length, as a function of pseudorapidity (full circles). The response is defined as the mean value of the measured energy loss spectrum truncated at 97.5% of total number of entries. Results are given on EM scale, multiplied by the factor e/μ=0.91 in addition. Geant4 MC simulation results are shown with open squares. Larger differences between data and MC are observed in the extended barrel (|η|>0.9), where the muon path length is more sensitive to the actual impact point.

The total ATLAS Tile calorimeter response to muons at pseudorapidity ±0.35 as a function of the muon energy for stand-alone testbeam configuration and corresponding GEANT4 MC simulation (geant4-09-02, Athena 15.0.0). The peak response is defined as the most probable value of the measured energy loss spectrum acquired from the Landau-Gaussian convolution fit, the truncated mean as the mean value of the measured energy loss spectrum truncated at 97.5% of total number of entries, the trimmed mean as the mean value of the measured energy loss spectrum calculated by discarding a 2.5% entries of the lowest and the highest response. The results are given on the EM scale 1.05 pC/GeV. Measurements were taken with several calorimeter modules.

The cell response of electrons entering the calorimeter modules exposed to the beam at incidence angle of 20 deg, normalized to beam energy, with one entry for each A-cell measured. The plot contains data at various energies ranging from 20 to 180 GeV. The mean value 1.050±0.003 pC/GeV defines the Tilecal EM scale factor. The RMS spread of (2.4±0.1)% is due to local variations in individual tile & tile/fiber responses as confirmed by special MC studies.

Noise in PMT#2 connected to cell A1 (LBC - Demonstrator).
Electronic noise RMS was evaluated for each channel of LBC using amplitude of the first sample.
Noise is about 0.75 counts for most of the channels.
N.B: In this part of the analysis true 12-bit ADC readout of new system was converted to 10 bits range, to be compatible with 10-bit readout in legacy system (i.e. actual signal in ADC counts is 4 times bigger).

Introduction

This page lists the public plots illustrating test beam results.

Test beam results

Electrons

The cell response of electrons entering the calorimeter modules exposed to the beam at incidence angle of 20 deg, normalized to beam energy, with one entry for each A-cell measured. The plot contains data at various energies ranging from 20 to 180 GeV. The mean value 1.050±0.003 pC/GeV defines the Tilecal EM scale factor. The RMS spread of (2.4±0.1)% is due to local variations in individual tile & tile/fiber responses as confirmed by special MC studies.

Muons

Example of the isolated muon signal as measured in the stand-alone calibration test beams of the calorimeter at η=0.35 in the whole tower (top) and in a cell of the last radial compartment (bottom). The EM scale is 1.05 pC/GeV. The signal is very well separated from the noise (shown by narrow peaks), the signal-to-noise ratio is ~44 (tower) and ~18 (last radial compartment) respectively. The last radial compartment can be used to tag muons inside jets. The response shown is associated with the full resolution data available at trigger level 2 and above.

muon_response_tower.pngmuon_response_dcell.png
The total calorimeter response to 180 GeV muons, normalized to the path length, as a function of pseudorapidity (full circles). The response is defined as the mean value of the measured energy loss spectrum truncated at 97.5% of total number of entries. Results are given on EM scale, multiplied by the factor e/μ=0.91 in addition. Geant4 MC simulation results are shown with open squares. Larger differences between data and MC are observed in the extended barrel (|η|>0.9), where the muon path length is more sensitive to the actual impact point.

The total ATLAS Tile calorimeter response to muons at pseudorapidity ±0.35 as a function of the muon energy for stand-alone testbeam configuration and corresponding GEANT4 MC simulation (geant4-09-02, Athena 15.0.0). The peak response is defined as the most probable value of the measured energy loss spectrum acquired from the Landau-Gaussian convolution fit, the truncated mean as the mean value of the measured energy loss spectrum truncated at 97.5% of total number of entries, the trimmed mean as the mean value of the measured energy loss spectrum calculated by discarding a 2.5% entries of the lowest and the highest response. The results are given on the EM scale 1.05 pC/GeV. Measurements were taken with several calorimeter modules.

Pions

Pion response vs. energy of incident pions at |η|=0.35
- Top: measurements were taken with many calorimeter modules and the response of each is normalized to the mean response at the common energy of 180 GeV. Open squares represent Geant4.8.3 Monte Carlo simulations, with QGSP and Bertini intranuclear cascade models.
- Bottom: experimental data corrected for longitudinal and transverse energy leakage as derived from data taken in special 90 deg configuration and Geant4 MC simulation. The energy dependence is due to calorimeter non-compensation; the displayed fit uses Groom's parametrization of the non-EM component of hadronic showers with F_h = (E_beam/E_0) ^m-1

pion_linearity_no_corr_at_all_label.pngpion_lin_fits_aver_1fixed_nomc_new1.png
The Tilecal-standalone energy resolution for pions impinging on the calorimeter at |η|=0.35 (equivalent calorimeter depth 7.9λ), as a function of the beam energy. MC simulation results (Geant4.8.3 QGSP+Bertini models, shown with open squares) are in agreement with data (full circles). The electronic noise contribution is found to be negligible so only statistical and constant terms are used in the fit.
Note that in the ATLAS configuration the total calorimeter (EM LAr + Tilecal) depth is larger by about 30%, hence the longitudinal leakage is smaller and its contribution to the energy resolution degradation is smaller (see also next plot). The expected constant term for jet energy resolution in ATLAS is typically 2.6% ( CERN-OPEN-2008-020, page 306, Table 3)

The dependence of the energy resolution of Tilecal on the depths of the calorimeter for pions as measured in the 90deg testbeam configuration. The resolution is defined as σ/peak of a Gaussian fit to the distribution in the range -2σ to 2σ around the peak value. The resolution is normalized to the one at 10.9 λ.

Comparison with Monte Carlo simulations

Visible energy in TileCal
Mean value of the energy released in TileCal by a pion beam at η=-0.35 of several energies. The mean is extracted with a 2 sigma Gaussian fit of the energy distribution. Experimental data and Monte Carlo simulations are calibrated to the electromagnetic scale using a sample of 20 GeV electrons. The exact beam composition is reproduced in the Monte Carlo samples.
Data obtained with TileCal standalone test-beam 2002 setup: a three layers stack with a prototype barrel module a production barrel module and two extended barrel modules on top.

Longitudinal shower shape
Fraction of the total energy released by a pion beam in each longitudinal sample of the Tile calorimeter. The first section (Sample A), of about 1.4 interaction length, samples the beginning of the shower development, the second (Sample BC) is the longest section (4λ) and contains the bulk of the hadronic shower. The last sample (Sample D) measures the energy in the tail of the shower.

Lateral shower shape
Lateral profile of the hadronic shower from a pion beam in TileCal. Ecore is the energy released in the projective tower hit by the pion beam (0.1x0.1 in ΔηxΔφ). The energy in the volume around this tower measures the size of the shower halo (Ehalo).

Sampling fraction

Reverse value of the sampling fraction (1/SF) as the function of pseudo-rapidity. The quantity is given by the ratio of beam energy over visible energy. The values are constant over a large -region. The increase of 1/SF at small can be qualitatively explained by the periodic iron/scintillator structure of the TileCal. In the simulation the energy deposited by particles in a cell at the EM scale in TileCal is calculated as the energy released in the scintillators multiplied by the factor determined at η=0.35 consistently with the EM scale used for the data obtained with electrons at Test Beams.

Determinations of ratio of the incident electron energy E over the simulated visible energy deposited in the cells 1/SF without and with the introduction of the U-shape in the Test Beams MC. The systematic error Δ_?imp corresponds to the uncertainty on the impact point of the electrons on the cell of about 20 mm in y at Test Beams. The diff erence of the values of 1/SF obtained using two diff erent methods Δ_?meth is smaller than 0.1%. The considered systematic errors do not a ffect the determinations of 1/SF without U-shape simulation.
