  2. Outline • Basics on Atlantis: • General setup, interface package JiveXML: modes to produce input data (file or online) • GUI of Atlantis, Projections • Trigger data in Atlantis: • ROIs • TriggerTowers and JetElements • Upcoming developments: • Trigger results in 12.0.0 AODs Trigger info in Atlantis event display, 29 June 06

  3. The event display Atlantis • http://www.cern.ch/atlantis • For general help, and suggestions, please contact: • atlantis.support@cern.ch • A tool for thevisual investigationand physical understandingof all typesof events inside ATLAS.. • And also useful to • help develop reconstruction and analysis algorithms • facilitate debugging during commissioning • create pictures and animations for presentations, • publications and exhibitions • use as online event display at the control room Trigger info in Atlantis event display, 29 June 06

  4. How the event display Atlantis works Try to put data from the ATLAS detector into the human brain in an intuitiveway, so the human may make fast and correct conclusions. This is largely accomplished by using data oriented projections. Atlantis has two parts: JiveXML:One inside the ATLAS software framework Athena in C++ to derive data running under Scientific Linux 3, AtlantisJava: and the actual interactive graphical tool as a standalone Java application, which can be run on any platform. Data transmission is done via XML files, IP connections or URL.The LHC is not yet running, therefore the events shown here are simulations using Monte Carlo methods and very detailed models of the interaction with the detector’s numerous layers and materials.

  5. Detector / Data Oriented Projections 3D Cartesian coordinates x,y,z are not always optimal for colliding beam experiments. More natural and useful are the non-linear combinations which reflect the design of ATLAS: r = sqrt(x2+y2) f = arctan(y/x)  = arctan( r/z) Atlantis offers e.g. the following projections: YX projection rZ projection V-Plot (fh) in 2D Legoplot 3D.

  6. Basics (1): Running JiveXML • Default mode: Athena package JiveXML dumps output file in xml format, to be read back into Atlantis (a Java standalone application) • Also possible to run over a large number of events and only display (produce xml files for) a selected few of them (JiveXML is now an AlgTool) • Default mode: Running from Digi, switch flag “doJiveXML=True” in RecExCommon/myTopOptions.py • Online mode: JiveXML constantly ‘feeds’ event data into IP port (used in InDet commissioning): Flags:doJiveXML = True TrueToolSvc.EventData2XML.OnlineMode = TrueToolSvc.EventData2XML.WriteToFile = False • New mode: Interactive Athena interface: Atlantis GUI sends commands back into Athena prompt (interactive re-vertexing) Trigger info in Atlantis event display, 29 June 06

  7. Basics (2): Atlantis (Java) • Website has plenty of documentation & tutorials: http://cern.ch/atlantis • Alias ‘atlantis’ available after setting up your Athena environment • Runs also under Windows / Mac as a java application (may require installing Java 1.5 SDK, but also runs with 1.4) Copy directory ‘AtlantisJava-*’ from release, start atlantis.jar • Note: Although Atlantis is inside the release, it has no dependency on other packages. It is a Java standalone application. Inclusion into release only to simplify distribution and code management. • The very latest Atlantis version is now available from the (any !) Offline release (package graphics/AtlantisJava): cmt co graphics/AtlantisJava cd AtlantisJava-*/cmt cmt config source setup.sh gmake java –jar atlantis.jar Trigger info in Atlantis event display, 29 June 06

  9. GUI: Data Selection for Trigger data Trigger info in Atlantis event display, 29 June 06

  10. ROIs (1) • eta/phi projection • EmTauROIs are green crossed rectangles fixed size • 4 EmTauROIs are visible here. (Semileptonic ttbar event, CSC 5200) • JetROIs would be red (none here) • “V” are tracks, red and green squares are calo cells • circles are reconstructed AOD objects (dark blue: BJet, light blue: TauJet, slim grey circle: ParticleJet) • Green/red squares: Calorimeter cells Trigger info in Atlantis event display, 29 June 06

  11. ROIs (2) … zoom area using “Rubberband” interaction in GUI … Trigger info in Atlantis event display, 29 June 06

  12. ROIs (3) … switch off Tracks (V’s) … Trigger info in Atlantis event display, 29 June 06
