Information Systems and Data Acquisition for
ATLAS
This team continues to consolidate its position
within the ATLAS Trigger and Data Acquisition
(TDAQ) group, in all areas it holds
responsibilities. We emphasize the achievements
in the TDAQ databases, the First Level Trigger
(FLT) electronics, and Calibration and Alignment
studies

• Weve participated in the ATLAS TDAQ Large Scale
  Tests and in the Inner Detectors Alignment
  effort
• Weve initiated the development of the Temporal
  Instrumental Database (TIDB2) a database C
  API for managing Interval of Validity (IOV) data,
  which uses a plug-in system to interface with
  several DBMSes (MySQL, PostgreSQL, Oracle, COOL)
  and data types (BUFR, GRIB, ROOT)
• Weve created a KDE/Qt-based browser
  (KTIDBExplorer) for database navigation. It uses
  TIDB2 for DBMS interface and its own plug-ins for
  visualization of extended data types, and will be
  the base of the
• Weve created the Online Asynchronous Interface
  to COOL (ONASIC), the successor to the TDAQ
  Online Conditions interface to log all
  information from the running Online system to the
  ATLAS Configuration Database
• Weve developed the OKS2COOL tool an interface
  between the Configuration Database (OKS) and
  ATLASs Main Database (COOL)
• Weve developed, tested and validated the Local
  Trigger Processor Interface Module hardware
  electronics
• Weve designed a Local Trigger Processor
  Interface Module (LTPIM) prototype and the VHDL
  codes for the full VME slave interface and module
  control

This team will maintain its decisive contribution
to the advancement of knowledge in the domain of
the information systems for HEP experiments, and
will solidify its role in the necessary
developments for the success of the ATLAS
experiment

• ATLAS Databases
• Test and validate ONASIC in the context of the
  TDAQ Online system and Configuration Databases,
  and integrate in the TDAQ online software bundle
• Develop the Online Objects Extended Database
  Browser (NODE), based on KTIDBExplorer a TDAQ
  Monitoring Working Group tool for navigating COOL
  tables and displaying ROOT histograms
• Test and validate OKS2COOL the interface
  between the Configuration and Main ATLAS
  databases, in the context of the Configuration
  Database group
• Develop a software tool (Controller) to perform
  stress tests on Offline Databases
• Research on a database interface for general
  scientific data objects (TIDB2). The task is
  conducted locally but reported to the ATLAS
  online database group
• First Level Trigger hardware electronics
• Complete test, validation and documentation of
  the LTPIM including combined tests with ATLAS
  test beam
• Calibration and Alignment
• Participation in the study and validation of the
  Calibration and Alignment strategies for the
  ATLAS detector, namely the Inner Detector
  calibration stream. We seek to obtain Calibration
  and Alignment constants in 24 hours, to be used
  in the first-pass reconstruction

Our software, developed for ATLAS, is part of the
LCG persistent framework
We use standard GNU tools for a portable
development strategy. We aim to make our
applications reusable in any environment and
platform
