Outline

• Atlantis philosophy
• Geometry CTB Geometry
• Online/Interactive event access
• Other new features (esp. Calorimeters)
• Plans

3
Atlantis philosophy

• Principles
• Visualise understand complete ATLAS events in
  all their complexity
• Hide the detector details in favour of clarity
  for the event data
• No operation (zoom, rotate, plot) should take
  more than a second (and most should take no
  time)

4
Geometry

• The simplified Atlantis geometry is produced by
  JiveXML in athena at initialization (using
  GeoModel)
• Set in jobOs (really only for experts)
• EventData2XML.WriteGeometry True
• Produces XML geometry files

5
Calorimeters in CTB

• Rotation tricky but now it works! (thanks to
  Claire)
• That was the last missing piece in having the
  full description of CTB. All detectors are now
  there!

6
CTB Rotation of Calorimeters

• A set of geometry files (h0.2, 0.3, ) to change
  
• Now possible to change geometry on the fly
• Contact us if you want geometry for your
  favourite value of h

Event access

• By default
• Run athena/JiveXML to produce XML event files
• (one per event)
• Look at the XML files with Atlantis
• Convenient independent
• Put Atlantis XMLs on laptop, look at them on
  the plane (laptop Mac, Linux, Windows)
• Also possible to read events from URL address
• But we would like also some more direct
  connection between athena and Atlantis

10
Interactive data access (I)

• Using xmlrpc client(atlantis) server(athena)
  protocol
• Run athena interactively (athena i) and add in
  jobOptions
• EventData2XML.OnlineMode True
• EventData2XML.ServerName hostname
• Then from Atlantis ask for next event
• or, for online running, set the refresh time
  (used in the CTB)

11
Interactive event access (II)
12
Interactive event access (III)

• All this works but there is more to do
• Would like to select three tracks in Atlantis and
  tell athena to run a vertex fitter on them
• Would like to re-run the jet clustering with
  different parameters and re-transmit back to
  Atlantis only the new jets (and associations)
• Save an event (in XML) that looks interesting
• These are all part of the long term plans (but
  interactive Athena running with python needs to
  improve too)

Atlantis in external sw area

• Until recently Atlantis was
• download-able from http//cern.ch/atlantis
• installed on /afs/cern.ch/atlas/project/Atlantis/c
  urrent
• In addition, now (soon after 9.3.0), Atlantis has
  been made an external package and will be
  distributed with the ATLAS sw releases.
• And a glue package will give you the alias
  atlantis so you will just need to type
  atlantis to run it with your local
  installation of ATLAS software

14
Calo requests

• Useful session with Calo community on 17/11
• Requested
• Logarithmic energy scale
• Grey-scale Colour coding for energy
• More projections
• Lego plot in eta-phi
• Explained existing Calo features
• Very useful interaction please help us to help
  you!

Plans till Easter

• Work on the Calo shopping list
• Follow-up new InDet EDM (JiveXML)
• Follow-up on Truth access changes (JiveXML)
• Developers documentation (plenty of User Help
  exists!)
• Work on other user requests

18
Longer term plans

• Re-design/structure JiveXML
• Beginner/Advanced user GUI
• Atlantis athena interaction
• More features (on demand), commissioning support,
  users support/training etc

Summary

• Atlantis is there to help reconstruction/physics
  communities
