1 Trigger information in the Atlantis event display Qiang Lu, Juergen Thomas, Peter Watkins (Birmingham) Hans Drevermann (CERN) Andrew Haas (Columbia) Eric Jansen, Pieter Klok, Charles Timmermans (Nijmegen, NIKHEF) Simon Dean, Nikos Konstantinidis, Zdenek Maxa (UCL) Level-1 Calorimeter Trigger Joint Meeting Rutherfold Lab, 29 June 2006

2 Trigger info in Atlantis event display, 29 June 062 Atlantis.Support@cern.ch http://cern.ch/atlantis 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

3 Trigger info in Atlantis event display, 29 June 063 Atlantis.Support@cern.ch http://cern.ch/atlantis The event display Atlantis http://www.cern.ch/atlantis For general help, and suggestions, please contact: atlantis.support@cern.ch A tool for the visual investigation and physical understanding of all types of 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

4 Trigger info in Atlantis event display, 29 June 064 Atlantis.Support@cern.ch http://cern.ch/atlantis How the event display Atlantis works Try to put data from the ATLAS detector into the human brain in an intuitive way, 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 Trigger info in Atlantis event display, 29 June 065 Atlantis.Support@cern.ch http://cern.ch/atlantis 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:  = sqrt(x 2 +y 2 )  = arctan(y/x)  = arctan(  /z) Atlantis offers e.g. the following projections: YX projection  Z projection V-Plot (  ) in 2D Legoplot 3D.

6 Trigger info in Atlantis event display, 29 June 066 Atlantis.Support@cern.ch http://cern.ch/atlantis 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 = True ToolSvc.EventData2XML.WriteToFile = False New mode: Interactive Athena interface: Atlantis GUI sends commands back into Athena prompt (interactive re- vertexing)

7 Trigger info in Atlantis event display, 29 June 067 Atlantis.Support@cern.ch http://cern.ch/atlantis 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
