Solid simulation with GEMC
For new users
GEMC is a wrapper around genat4. It's like a great genat4 example code, but makes detector geometry, material, sensitivity etc outside of source code and loadable on run time. It also make simulation output into standard format and can take input from event generators. Read the general GEMC info on its website to learn what it is. In particular take a look at the GEMC tutorials.
SoLID GEMC is what we use GEMC to do SoLID simulation. It includes SoLID detector definition, running script, output analysis code etc.
Check out the quick start, installation and running guide to run GEMC with Solid configuration.
Finally you can go through rest of items to really start using it.
Many information are cross linked through pages even with SoLID hardware design and software analysis. So make sure to browse around.
Quick start
- note
- make sure you have no other environmental variable set at login which may have conflict with GEMC. one way to do it is to rename .cshrc and .login to something else and log out and then in again
on ifarm using pre-compiled GEMC instllation
svn checkout https://jlabsvn.jlab.org/svnroot/solid/solid_gemc cd solid_gemc/script source set_solid run_solid_CLEO_PVDIS_inter (this will show SoLID PVDIS setup) run_solid_CLEO_SIDIS_3he_inter (this will show SoLID SIDIS setup) run_solid_CLEO_PVDIS_batch (this will produce SoLID PVDIS output) run_solid_CLEO_SIDIS_3he_batch (this will produce SoLID SIDIS output)
on any machine using a local GEMC installation
download and install GEMC by following the installation instruction install svn checkout https://jlabsvn.jlab.org/svnroot/solid/solid_gemc modify solid_gemc/script/set_solid to your local setting and then source it If your machine is outside of Jlab network, try tunnel through jlab firewall with your jlab account to access solid database server, refer to mysql database put a copy of SoLID CLEO magnetic field map file solenoid_CLEO.dat at where defined by the FIELD_DIR option then you can run the script like run_solid_CLEO_PVDIS_inter, run_solid_CLEO_SIDIS_3he_inter,run_solid_CLEO_PVDIS_batch, run_solid_CLEO_SIDIS_3he_batch refer to details in run

Things to know
Use a graphic SVN to monitor code change with alert
GEMC ouput with unit MeV, mm, ns in flux and gen banks, we should keep the same unit for newly generated banks.
GEMC doesn't record passby particles which deposit zero energy in the sensitive area. To record it by option "-RECORD_PASSBY=1"
install GEMC for SoLID simulation
run GEMC with SoLID configuration
mysql database
define geometry/material/sensitivity
magnetic field map
hit processing
simulation output
event generator
Visualization through GDML and directly through GEMC
Simulation Study
acceptance
