After making the compact.xml, you have to convert to a lcdd file ( for SLIC) and a heprep file (later, for org.lcsim and wired). both can be done using GeomConverter.
The next step is to make a little macro for SLIC to use the particle gun and generate a few events. This is sample:
| Code Block |
|---|
/lcio/PDGFlag true /generator/select gun /gun/position 0 0 0 /gun/direction 0. 0. 1 /gun/energy 10 GeV /gun/particle neutron /lcio/filename slic_clichcalstack_neutron_10GeV_Wscint.slcio /lcdd/url /home/marcel/demo/stack/clichcalstack.lcdd /run/beamOn 125 |
The particle Gun is set up as
| Code Block |
|---|
/generator/select gun /gun/position 0 0 0 /gun/direction 0. 0. 1 /gun/energy 10 GeV /gun/particle neutron |
This creates a particle gun and 0/0/0 firing along the z-axis using neutrons at 10 GeV, a list of particles is available in the GEANT manual common examples are gamma, electron, neutron...
| Code Block |
|---|
/lcio/filename slic_clichcalstack_neutron_10GeV_Wscint.slcio /lcdd/url /home/marcel/demo/stack/clichcalstack.lcdd |
this two lines specify the outputfile name and location and the location of lcdd file created with GeomConverterFinally, you decide how many events you want, in this example 125
Start SLIC using
| Panel |
|---|
SimDist/scripts//slic.sh -m slic.macro |
and off you go
