Introduction

Approved plots that can be shown by ATLAS speakers at conferences and similar events. Please do not add figures on your own. Contact the responsible LAr project leader in case of questions and/or suggestions.

The Liquid Argon Calorimeter performance plots displayed here were obtained using LHC stable beam collision events recorded by ATLAS in April 2024 at an injection energy of 6.8 TeV per beam.

FEB Offset Timing

Average time per Front End Board (FEB) in the Liquid Argon (LAr) Electromagnetic Barrel (EMB) Calorimeter collected with the first stable beam collision data at √s = 13.6 TeV, taken in April 2024. The average time for one FEB is the result of a Gaussian fit on the time distribution from pulses reconstructed from medium and high gain for all channels of this FEB. All 896 FEBs are well aligned and no significant outliers are observed.

Average time per Front End Board (FEB) in the Liquid Argon (LAr) Electromagnetic End-cap (EMEC) Calorimeter collected with the first stable beam collision data at √s = 13.6 TeV, taken in April 2024. The average time for one FEB is the result of a Gaussian fit on the time distribution from pulses reconstructed from medium and high gain for all channels of this FEB. All 552 FEBs are well aligned and no significant outliers are observed.

Average time per Front End Board (FEB) in the Liquid Argon (LAr) Hadronic End-cap Calorimeter (HEC) collected with the first stable beam collision data at √s = 13.6 TeV, taken in April 2024. The average time for one FEB is the result of a Gaussian fit on the time distribution from pulses reconstructed from medium gain for all channels of this FEB. All 48 FEBs are well aligned and no significant outliers are observed.

Average time per Front End Board (FEB) in the Liquid Argon (LAr) Forward Calorimeter (FCAL) collected with the first stable beam collision data at √s = 13.6 TeV, taken in April 2024. The average time for one FEB is the result of a Gaussian fit on the time distribution from pulses reconstructed from medium gain for all channels of this FEB. All 28 FEBs are well aligned and no significant outliers are observed.

Comparison of the mean time measured per Front-End Board (FEB) in the Liquid Argon (LAr) Calorimeters, with the first stable beam collision data at √s = 13.6 TeV, between two typical runs taken in May 2023 and April 2024. No timing adjustments were done between the two periods. The mean time for one FEB is the result of a Gaussian fit on the time distribution from pulses reconstructed from medium and high gain for all channels of each FEB in the LAr Electromagnetic Barrel (EMB) and End-cap (EMEC) Calorimeters, and medium gain for each FEB in the Hadronic Calorimeter (HEC) and Forward Calorimeter (FCAL). The distribution of this difference shows a mean timing stability per FEB between the two runs of the order of 100 ps.

Local page variables

This section contains local page variables that you can use in editing this page to avoid hardcoding long paths etc.

To use the variable, just enclose it with %, like: %IMG{name}% which will turn into File 'name' not found! automatically.

If you require to introduce a new variable, simply add it to the list below.

  • Set IMGNAME = %IF{"attachments[name='%DEFAULT{default="fig1"}%.png']" then="%DEFAULT{default="fig1"}%.png" else="%IF{"attachments[name='%DEFAULT{default="fig1"}%.jpg']" then="%DEFAULT{default="fig1"}%.jpg" else="%IF{"attachments[name='%DEFAULT{default="fig1"}%.jpeg']" then="%DEFAULT{default="fig1"}%.jpeg" else="File '%DEFAULT{default="fig1"}%' not found!"}%"}%"}%
  • Set IMGPATH = /twiki/pub/AtlasPublic/LArCaloPublicStableBeam2024/%IMGNAME{%DEFAULT{default="fig1"}%}%
