Two LAr Phase I trigger upgrade demonstrator boards (2 Demonstrator LTDBs, LAr Trigger Digitizer Boards) were installed insitu on the LAr detector in July 2014 (coverage: 9π/16 < φ < 11π/16, 0 < η < 1.4). To receive the digital supercell energies ABBA boards (LDPB preprototype) were installed in USA15. One ABBA board receives data from one LTDB 320 super cells. Supercell data has been recorded for a large number of time slices with this preprototype backend electronics.
Correlation of energy measurements for each layer: The measured supercell (SC) energies of the LAr Phase I demonstrator are compared to summed LAr cell energies in ATLAS for E_{SC} > 1 GeV. The supercells in the presampler, front, middle and back layer consist of 4, 8, 4 and 8 LAr cells, respectively. Good agreement is observed between the two readouts.



Difference of energy measurements for each layer: The measured supercell (SC) energies of the LAr Phase I demonstrator are compared to summed LAr cell energies in ATLAS by calculating the difference (E_{SC} − Σ_{SC} E_{cells}) for E_{SC} > 2 GeV. The supercells in the presampler, front, middle and back layer consist of 4, 8, 4 and 8 LAr cells, respectively. Good agreement is observed between the two readouts. The width of the distribution is compatible with the expected noise level. The shift of the means is due to the preliminary calibration of the supercells.

Supercell pulse shapes for each layer:
Responses of four super cells (one from each layer) from the LAr Phase I demonstrator installed in ATLAS to injected calibration pulses (DAC = 1000 counts to each LAr cell), the equivalent energy for DAC = 1000 is shown in subsequent plots.
The super cell outputs are the sums of 4, 8, 4 and 8 LAr cells for Presampler, Front, Middle and Back layer, respectively.
Size and shape of pulses are as expected and vary due to different detector and electronics properties.


Pulse maximum in ADC counts for each layer:
Rapidity dependence of the pulse maximum in ADC counts (pedestal subtracted) for the super cells from the LAr Phase I demonstrator in ATLAS for injected calibration pulses (DAC = 1000 counts to each LAr cell), the equivalent energy for DAC = 1000 is shown in subsequent plots.
The super cell outputs are the sums of 4, 8, 4 and 8 LAr cells for Presampler, Front, Middle and Back layer, respectively.
The variations in response, especially in the back layer and at η = 0.8, are due to the change in electrode segmentation, calibration and readout electronics.


Equivalent transverse energy for each layer:
Rapidity dependence of the equivalent transverse energy for an injected calibration pulse of DAC = 1000 counts into each LAr cell.
The super cell outputs are the sums of 4, 8, 4 and 8 LAr cells for Presampler, Front, Middle and Back layer, respectively. The jump seen at η = 0.8 reflects the change of absorber thickness, electrodes and calibration resistors.


Noise level of super cells in ADC counts:
Rapidity dependence of the noise (RMS) in ADC counts for the super cells from the LAr Phase I demonstrator in ATLAS.
The super cell outputs are the sums of 4, 8, 4 and 8 LAr cells for Presampler, Front, Middle and Back layer, respectively.
The jump seen at η = 0.8 reflects the change of electrodes’ segmentation at that position. The noise level is well below 1 ADC count and consistent with test bench measurements.


Noise level of super cells in transverse energy:
Rapidity dependence of the noise (RMS) in transverse energy for the super cells from the LAr Phase I demonstrator in ATLAS.
The super cell outputs are the sums of 4, 8, 4 and 8 LAr cells for Presampler, Front, Middle and Back layer, respectively.
The jump seen at η = 0.8 reflects the change of absorber thickness, electrodes and calibration resistors.
The noise level is as expected between 100 and 250 MeV per super cell.


Pulse shapes of a front layer super cell:
Pulse shapes of a super cell from the LAr Phase I demonstrator installed in ATLAS for injected calibration pulses with different amplitudes (DAC = 2000, 4000, 6000, 8000, 10000 counts), the equivalent energy for these DAC values is shown in subsequent plots.
The super cell outputs are the sums of 8 LAr front layer cells.
Size and shape of pulses are as expected and show good linearity up to DAC = 8000, while beyond, analog saturation occurs upstream of the demonstrator board.


Pulse maximum versus DAC value:
Pulse maximum (in ADC counts) for four different super cells from the LAr Phase I demonstrator installed in ATLAS for injected calibration pulses with different amplitudes (DAC = 2000, 4000, 6000, 8000, 10000 counts), the equivalent energies for these DAC values are shown in subsequent plots.
The supercell outputs are the sums of 8 (4) LAr front (middle) layer cells.
Good linearity up to DAC = 8000 (DAC = 6000) for the front (middle) layer is observed, while beyond, analog saturation occurs upstream of the demonstrator board.


Pulse maximum versus transverse energy:
Pulse maximum (in ADC counts) for four different super cells from the LAr Phase I demonstrator installed in ATLAS for injected calibration pulses with different amplitudes (DAC = 2000, 4000, 6000, 8000, 10000 counts), plotted in units of equivalent transverse energy.
The supercell outputs are the sums of 8 (4) LAr front (middle) layer cells.
Analog saturation upstream of the demonstrator board occurs at different transverse energy values depending on the calorimeter layer and rapidity.


Total noise on the trigger readout path of the demonstrator test setup: Here the RMS on the trigger readout path in MeV is shown. It was measured in a setup which is equivalent to a crate in ATLAS, with a halffull Front End Crate (FEC) equipped with Front End Boards (FEBs). Trigger towers 114 correspond to an etaregion of 0 to 1.4. Trigger towers 1629 are the same in eta, but adjacent in phi. The values represented by the full circles were measured by a spectrum analyzer, the values shown in open circles were measured with Flash ADCs. For the computation a pedestal run with 5000 events and 8 samples was used. 

Fraction of total noise which is coherent for Phase I demonstrator measured in ATLAS: Here the total noise which is coherent is shown as fraction of the total noise per readout channel (Coherent Noise Fraction = CNF) The CNF for feedthroughs (FT) 712 on the detector has been computed, of which FT 9 and 10 belong to the demonstrator crate I06, FT 7 and 8 to I05 and FT 11 and 12 to I07. For the computation a pedestal run with 40000 events and 32 samples was used. The board in the first slot reads out the presampler, the boards in the following seven slots read out the front layer, the next two boards the back layer and the last four boards the middle layer of the calorimeter. The last entry is the CNF of the whole halfcrate. The coherent noise fraction rho was calculated using the formula in this link. 

LAr Trigger Digitizer Board (LTDB) demonstrator noise measured on the demonstrator installed in ATLAS: Here, the RMS of the 12bit ADC of the 320 channels of the LTDB demonstrator measured in USA15 is shown. For the computation a pedestal run with 16384 events was used. One ADC count corresponds to roughly 125 MeV.. 

LAr Trigger Digitizer Board (LTDB) demonstrator pedestal measured on the demonstrator installed in ATLAS: Here, the pedestal values of the 12bit ADC of the 320 channels of the LTDB demonstrator measured in USA15 are shown. For the computation a pedestal run with 16384 events was used. 

Total noise on main readout of calorimeter cells of demonstrator crate I06 (ATLAS): In this plot, the RMS of the 128 channels of the Front End Boards (FEBs) of the demonstrator crate installed in ATLAS is shown. The FEBs read out the calorimeter cells. There are 28 such boards in one Front End Crate (FEC). The FEBs read out signals from different layers of the calorimeter. The noise levels of the boards vary because different capacitances and gains are applied to their respective cells. For the computation of the RMS a pedestal run with 3000 events and 32 samples was used. The noise level is not higher compared to the neighboring crates on the detector (e.g. see plots for crate I05). 

Total noise on main readout of calorimeter cells of crate I05 (ATLAS): In this plot, the RMS of all channels of the FEBs of one of the neighbour crates (I05) of the demonstrator crate I06 in ATLAS is shown. For the computation of the noise a pedestal run with 3000 events and 32 samples was used. 

Estimated quantization noise as function of energy in the front layer of the LAr EM barrel calorimeter, with the two gain system proposed for the PhaseII LAr Calorimeter readout (low gain curve in red, high gain curve in blue). The quantization noise curves assume the use of a 12bit successive approximation register (SAR) with a dynamic range enhancer (DRE) to obtain a 14bit ADC with 12bit precision. Gain switching occurs close to the highest energy digitized in the high gain.

Bipolar shapers can have different numbers of integration stages, as well as various peaking times, which both affect the total noise (electronics plus pileup) on the analog pulse of the PhaseII LAr Calorimeter readout. The figure shows the total noise as a function of the level of pileup, μ, for a cell from the EM middle layer at η = 0.5, obtained after optimal filtering, for different number of integration stages in the shaper. The optimal filtering coefficients (OFC) are computed for each case separately. No significant differences in the noise level can be seen in the EM case. These results do not include a detailed simulation of the electronics circuit, which could affect the results.


Bipolar shapers can have different numbers of integration stages, as well as various peaking times, which both affect the total noise (electronics plus pileup) on the analog pulse of the PhaseII LAr Calorimeter readout. The figure shows the total noise as a function of the level of pileup, μ, for a HEC cell in the first layer at η = 2.35, obtained after optimal filtering, for different number of integration stages in the shaper. The optimal filtering coefficients (OFC) are computed for each case separately. For the HEC, a CR(RC)^{3} shaper improves the noise by 5% over a CR(RC)^{2}. These results do not include a detailed simulation of the electronics circuit, which could affect the results.

Simulated noise in the Liquid Argon and Tile calorimeters at the electron scale (bunch spacing t=25ns): Quadratic sum of simulated electronics and pileup noise per calorimeter cell for each calorimeter layer as function of pseudorapidity. The pileup simulation is done by overlaying GEANT4 simulated events from PYTHIA (v6.4) including non diffractive and diffractive events. The overlay takes into account the full sensitive time of the detector (~500ns for the LAr) and the bunch train structure. For protonproton collisions at √s = 14TeV and a bunch spacing of t=25ns. The luminosity and corresponding average overlaying interactions per bunch crossing <µ> (pileup events) are specified below (and inside) each figure. The standard ATLAS electronics are assumed in the simulation. A comparison of data and MC for <µ> = 0 and <µ> = 14 can be seen at the corresponding links for the LAr and for the Tile calorimeter.

The below results are based on simulated VBF 2.6 TeV Higgs boson production and dijet production at 14 TeV with μ=190200 assuming the current ATLAS FCal, a highgranularity sFCal and the FCal with reduced acceptance
Total Noise Ratio: Noise ratio per calorimeter cell as a function of η for all layers for a high granularity sFCal over FCal at a centreofmass energy of 14 TeV and for a mean number of pileup event of μ=200. Small deviations from 1 in the innermost (s)FCal1 and full (s)FCal2/3 layers are due to the 6% denser sFCal1 compared to FCal1 which causes inelastic pp collisions to deposit more energy in the first module. In the outer region of sFCal1 the noise is 0.4 times the FCal1 noise. The ratio 1.1/0.4 = 2.75 of ratios for inner over outer cells is nontrivial and indicates that an sFCal with finer granularity improves the separation of hardscatter signal from pileup. The granularity ratio is 4. Therefore a double ratio of 4 would mean no improvement at all since all small cells would be fully correlated. A double ratio of 2 would be the maximal possible improvement in case all small cells are uncorrelated. 2.75 lies between these extremes, and since it is smaller than 4 means that the increase in granularity helps to suppress pileup. 

Number of Jet Constituents: Distribution of the number of constituents (clusters) for quark jets produced in the vectorboson fusion process 𝑝𝑝 → 𝐻 𝑞𝑞 → 𝑙^{−}𝑣 𝑙^{+}𝑣 𝑞𝑞 at 14 TeV centreofmass energy simulated for the current ATLAS FCal, a highgranularity sFCal, and three scenarios with reduced FCal acceptance. The increase in granularity and better separation of signal from pileup leads to larger number of constituents in the sFCal compared to FCal. The vectorboson fusion events were simulated with the Powheg and Pythia8 Monte Carlo generators in narrowwidth approximation for a hypothetic Higgs boson mass of 2.6 TeV and an average number of pileup events, μ, between 190 and 210. 

Cell Significance: Cell significance (E_{cell}/σ_{cell}) for the cell with the largest absolute cell energy over total noise simulated for the current ATLAS FCal, a highgranularity sFCal, and three scenarios with reduced FCal acceptance. Clusters are seeded when the absolute ratio is above 4. Cluster splitting can lead to entries with smaller ratios. The sFCal distribution is enhanced on the positve side while it remains close to the FCal distribution on the negative side. The negative entries are due to pileup only, while on the positve side signal and pile up contribute. The increase of mainly the positive side indicates that the signal detection ability is improved for the sFCal while the background remains on the same level. The distributions are obtained for vectorboson fusion events 𝑝𝑝 → 𝐻 𝑞𝑞 → 𝑙^{−}𝑣 𝑙^{+}𝑣 𝑞𝑞 at 14 TeV centreofmass energy, simulated with the Powheg and Pythia8 Monte Carlo generators in narrowwidth approximation for a hypothetic Higgs boson mass of 2.6 TeV and an average number of pileup events, μ, between 190 and 210. 

Average p_{T} Density: Shown is the simulated profile of the average median p_{T} density, ρ, evaluated from positiveenergy cell towers in the ATLAS LAr calorimeters. For the forward calorimeter, five different scenarios are studied: the current ATLAS FCal, a highgranularity sFCal, and three scenarios with reduced FCal acceptance. When a ρbased pileup suppression will be applied in the jet reconstruction it is expected that a larger amount of p_{T} will be removed for jets in the forward region in case of the sFCal. The distributions are obtained for vectorboson fusion events 𝑝𝑝 → 𝐻 𝑞𝑞 → 𝑙^{−}𝑣 𝑙^{+}𝑣 𝑞𝑞 at 14 TeV centreofmass energy, simulated with the Powheg and Pythia8 Monte Carlo generators in narrowwidth approximation for a hypothetic Higgs boson mass of 2.6 TeV and an average number of pileup events, μ, between 190 and 210. 

Number of Jets: Simulated integral jet p_{T} distribution for hard scattering and pileup jets and the relative fraction of hard scattering jets detected in the ATLAS FCal and in a highgranularity sFCal. An areabased p_{T} subtraction is applied. The amount of p_{T} subtracted from a jet is increased by a factor of 10 (thereby effectively killing the jet) in the case that it fails one of the jet shape variable cuts, which are based on jet width, transverse momentum sum of the jet constituents relative to the jet direction and the electromagnetic energy fraction. The distributions are obtained for vectorboson fusion events 𝑝𝑝 → 𝐻 𝑞𝑞 → 𝑙^{−}𝑣 𝑙^{+}𝑣 𝑞𝑞 at 14 TeV centreofmass energy, simulated with the Powheg and Pythia8 Monte Carlo generators in narrowwidth approximation for a hypothetic Higgs boson mass of 2.6 TeV and an average number of pileup events, μ, between 190 and 210. 

Ratio of PileUp Jets: Ratio of number of identified pileup jets and total number of reconstructed jets as a function of efficiency for determining a hardscattering jet as simulated in dijet events at 14 TeV for the ATLAS FCal and a highgranularity sFCal. All jets are selected in the pseudorapidity range 3.8<η<4.2 and in the p_{T} range between 50 GeV and 70 GeV. Also shown is the double ratio comparing the sFCal and FCal performance. The jet classification was performed using a likelihood ratio constructed from the jet width, the jet mass, the transverse momentum sum of the jet constituents relative to the jet direction, and the number of jet constituents (clusters). 

Number of PileUp Jets: Number of identified pileup jets per event as a function of efficiency for determining a hardscattering jet in highmass VBF Higgs events at 14 TeV for the ATLAS FCal and a high granularity sFCal. All jets are selected in the pseudorapidity range 3.2<η<3.8 and in the p_{T} range above 20 GeV. The jet reconstruction requires a positive clustervertexfraction and a pile up correction based on the average median p_{T} density, ρ, evaluated from positiveenergy cell towers in the ATLAS LAr calorimeters. The simulation of charged particle tracks is based on the ITk tracking system assuming a tracking coverage of η<4 and an ideal ITk detector resolution. The distributions are obtained for vectorboson fusion events 𝑝𝑝 → 𝐻 𝑞𝑞 → 𝑙^{−}𝑣 𝑙^{+}𝑣 𝑞𝑞 at 14 TeV centreofmass energy, simulated with the Powheg and Pythia8 Monte Carlo generators in narrowwidth approximation for a hypothetic Higgs boson mass of 2.6 TeV and an average number of pileup events, μ, between 190 and 210.
