Creating a Detector from compact.xml

Creating a compact.xml

• compact.xml is a human readable geometry description for slic. The best way to start is to take an existing compact.xml and modify it to your needs.

Setting up GeomConverter

• a detailed tutorial can be found here
• go to your GeomConverter directory, for example /usr/sbin/local/GeomConverter/
• build it using maven 2

  mvn -DskipTests=true clean install

• add the bin to your PATH variable

  export PATH=$PATH:/usr/local/sbin/GeomConverter/target/bin

• typing `GeomConverter` will now open a GUI to convert a compact.xml file either to an *.lcdd or a *.heprep file
• as an alternative one can use

  GeomConverter [-o format] [<infile> [<outfile>]]

Creating geometry files and checking for overlaps

• create the .heprep and .lcdd from the compact.xml
• use slic to check the lcdd file for overlaps
  • create a makro with the following line:

    /geometry/test/recursive_test

  • run slic with the macro

    slic.sh -g <detectorname>.lcdd -m macro

Making the detector known to org.lcsim

• a detailed tutorial can be found here
• create the file ~/.lcsim/alias.properties
• add the path of your detector definition files (*.lcdd and *.heprep) to alias.properties

  DETECTORNAME: file:///pathtodetectorfiles/

• The path must contain a file named detector.properties which has to contain the following line: name: DETECTORNAME
• remember to name your files `DETECTORNAME.heprep`
• sample file for the clic000 detector on the common afs space
