In this exercise we will use LCDD, an extension of the standard Geant4 GDML format, to describe a complete detector setup, including sensitive detectors and readout. Since we are using XML to configure Geant4 there is no need to write any C++ code we can use a version of SLIC which has been pre-built with support for GDML included. In this example we will use a simple test beam like calorimeter consisting of lead glass blocks of 1 cubic cm. For each calorimeter cell we read out the Ionization loss as well as the energy deposited by cherenkov photons. Example Example LCDD files, macros to run SLIC and java programs to analyze the LCIO output file files from within JAS3 are provided and are attached to this document.
