Introduction

SoLID detector simulation program "solid_gemc" is based on "GEMC 2.x" with additional hit process routine and outputs for all detector systems in SoLID.

It's located SoLID repository https://jlabsvn.jlab.org/svnroot/solid/solid_gemc2 with source codes and detector configuration, field, scripts etc.

You need both the jlab framework and SoLID repository before you can compile and run solid_gemc, refer to the quick start section

The "set_solid" script is used to setup env

sort by "Last modified" to see latest

compile and run

Once you complete the setup procedure, you can now compile "solid_gemc"

source your set_solid if you haven't done so
cd $SoLID_GEMC/source/$GEMC_VERSION
scons OPT=1
(then go to a clean terminal and source your set_solid so that "solid_gemc" can found in default PATH)
solid_gemc    (a empty graphic window with simulation setup should show up and confirm it's working, then you can move on full or subsystem simulation)

full simulation

All subsystems have their own "production" version directories "ec,hgc,lgc,gem,mrpc,spd,magnet,baffle,target,beamline,absorber" at "https://jlabsvn.jlab.org/svnroot/solid/solid_gemc2/geometry/"

Run full SoLID simulation in graphic mode with all subsystems together by

source your set_solid
cd $SoLID_GEMC/script
solid_gemc solid_PVDIS_LD2_full.gcard
solid_gemc solid_SIDIS_He3_full.gcard
solid_gemc solid_SIDIS_NH3_full.gcard
solid_gemc solid_JPsi_LH2_full.gcard

subsystem simulation

"solid_gemc" can be used for individual sub-detector systems and the whole detector simulation.

Each of sub-detector systems can do simulation independently and ready to merge it back into the whole system simulation.

They are considered "devel" version and located in their individual directories and person responsible as below

These directories should be kept clean so it only has files necessary for simulation, and ready to copy into the "production" area to be used with other subsystems

For all other files, please put them into other directories under the same subsystems.

Please refer to "hgc_solid_gemc" and "hgc" as an example

Once you think your subsystem devel version is ready, before making it a production version, be sure to test it with full simulation, meaning it has no conflict with any other production subsystem.

copy, paste and modify "$SoLID_GEMC/script/solid_*_full.gcard" to mix your devel version system and other production subsystems to test

After verify no conflict, you may release it as production version by copying ONLY necessary files like all perl script and txt files without any change into its production directory.

example

The root tree output can be analysis by some very simple scripts here https://jlabsvn.jlab.org/svnroot/solid/solid_gemc2/analysis/

header tree and generated tree

header tree and generated tree are direct passing through from input, either particle gun or lund file produced by a generator, referring to [1]

For generator used for SoLID, "eicRate" and "halld" both use header defined here https://hallaweb.jlab.org/wiki/index.php/Solid_eventgenerator#Output_file

flux tree

detector ID for flux hit processing

We use built-in flux hit processing for virtual planes near to real detectors to record particles entering or leaving real detectors

Each virtual plane has a unique id to identify it and it appears in the "id" branch of "flux" tree

Its ID is defined by 7 digits integer like "abcdefg"
a: detector
   GEM 1, CC 2, EC 3, MRPC 4, SPD 5, muon 6
