Info
introduction
Here is the information hub for SoLID software.
The software is based on GEMC framework for detector simulation, The physics event generation is independent.
The instruction for installation and how to use do event generation, simulation and reconstruction are listed below.
Installation
introduction
Physics event generation is a collection of independent software packages.
Detector simulation is based on Geant4 based simulation framework GEMC http://gemc.jlab.org
SoLID repository https://jlabsvn.jlab.org/svnroot/solid is for all of SoLID software
You need install both the framework and SoLID repository to use the software
installation of framework
The framework use environmental variable JLAB_VERSION to control version, SoLID use devel version currently, so do this "setenv JLAB_VERSION devel" when needed
The framework was tested on many platforms, but for SoLID use, it's only fully tested on Redhat flavoured linux like CentOS, RHEL, Fedora so far
Detailed instruction is here installation of framework
installation of SoLID repository
download by svn checkout
use a graphic SVN client to get auto notification of file update, for example kdesvn
svn co https://jlabsvn.jlab.org/svnroot/solid dir structure "evgen", some event generators, (the others are in other repositories, see event generation section for details) "solid_gemc2", GEMC related files for SoLID simulation "ec","cc","gem","mrpc" for individual systems
A personal copy of EIC repository at /home/zwzhao/solid/solid_svn/solid/ on ifarm
You should download your own copy on ifarm or you local machine so you can tweak the code
Coordinate System
SoLID uses the coordinate system below as "lab frame" for event generator output, detector arrangement and reconstruction
beam interaction point is at the origin. both beams are in the horizontal plane in the experimental hall which is xz plane in the frame. electron beam along -z axis, ion beam 50mrad away from +z axis with positive x component. for example, 5GeV electron has momentum (0,0,-5) and 100GeV ion has momentum (100*sin(50e-3),0,100*cos(50e-3))
