Abstract

An integrated system for data quality and conditions assessment for the ATLAS Tile Calorimeter is known amongst the ATLAS Tile Calorimeter as the Tile-in-One. It is a platform for combining all of the ATLAS Tile Calorimeter offline data quality tools in one unified web interface. It achieves this by using simple main web server to serve as central hub and group of small web applications called plugins, which provide the data quality assessment tools. Every plugin runs in its own virtual machine in order to prevent interference between the plugins and also to increase stability of the platform.

Highlights

ATLAS [1] is one of the two large general-purpose detectors at the Large Hadron Collider (LHC) at CERN
The ATLAS detector investigates a wide range of physics, from the Higgs boson and other Standard Model studies to the searches of extra dimensions and particles that could make up dark matter
It is expected that the majority of the plugin developers will not be sufficiently skilled in web development, the platform will provide setup scripts to setup a Virtual Machine (VM) and three plugin templates for the web application

Summary

ATLAS Tile Calorimeter

ATLAS [1] is one of the two large general-purpose detectors at the Large Hadron Collider (LHC) at CERN. The Tile Calorimeter (TileCal) [3], shown, is located in the central section of the ATLAS hadronic calorimeter It detects hadrons, jets and taus, while contributing to the jet energy and missing ET reconstruction, as well as assisting the spectrometer in the identification and reconstruction of muons. The TileCal is a sampling calorimeter using plastic scintillating tiles as the active medium and steel plates as the absorber It covers the pseudorapidity range up to |η| < 1.7 with one. The seven consecutive samples are combined by the electronics in a remote counting room, at a rate of up to 100 kHz, to compute the pulse amplitudes and their position in time These quantities are required for energy reconstruction
