full simulation and file sharing
We will run full simulation with all subsystems and generate various files at a shared central location
They can used for studies like acceptance,trigger, background, GEM etc and ensure consistent results
The file size is large in order of 50GB, you can transfer them by using "scp jlabname@ftp.jlab.org:file" or other ways here https://cc.jlab.org/filetransfers
- sharing location
location on disk /volatile/halla/solid/sim/solid_gemc location on tape /mss/halla/solid/sim/solid_gemc/ dir PVDIS_LD2_JLAB_VERSION_1.2 PVDIS_LD2_JLAB_VERSION_1.3 SIDIS_He3_JLAB_VERSION_1.2 SIDIS_NH3_JLAB_VERSION_1.3 JPsi_LH2_JLAB_VERSION_1.2 subdir pass1 pass2 pass3 pass4 ... refer details /home/zwzhao/solid/solid_svn/study/background/log_PVDIS_LD2 /home/zwzhao/solid/solid_svn/study/background/log_SIDIS_He3 /home/zwzhao/solid/solid_svn/study/background/log_SIDIS_NH3 /home/zwzhao/solid/solid_svn/study/background/log_JPsi_LH2
- file name example
"*BeamOnTarget_1e9_skim.root", created by shooting 1e9 electron on target, full SoLID simulation, only events has any entry in any detector is kept, physics list used is "QGSP_BERT_HP+STD+Optical", including hadron,EM and optical process "*BeamOnTargetEM_1e9_skim.root", created by shooting 1e9 electron on target directly, only events has any entry in any detector is kept, physics list used is "STD+Optical",meaning no hardon, only EM and optical process "*dirty_weighted_eDIS_filenum100_1e6.root, *dirty_normalized_*_pi*HallD_filenum500_5e6.root, *dirty_normalized_*_allnoeHallD_filenum500_5e6.root" dirty means full SoLID simulation with physics list "QGSP_BERT_HP+STD+Optical" weighted means the generator events distribute evenly in certain kinematic space,then have weight linked to crossection and rate normalized means the generator events distribute according to crossection by probability and weight is a constant for each event eDIS means electron from target by the DIS electron generator mode in "eicRate" code pion*HallD means pion from target by the modified hallD generator allnoeHallD means all particles from the modified hallD generator which has no electron 5e6 are number of event filenum500 means sum of 500 small files of 1e4=5e6/500 events each
- note about normalization factor
for BeamOnTarget skim file, (current in A)/1.6e-19/(number of event) = rate in Hz, for PVDIS_current=50uA,SIDIS_He3=15uA,SIDIS_NH3=100nA,JPsi=3uA, number of event is in file name, which is not number of tree entries in skim root file for other file, (var8->at(0) in tree header)/filenum = rate in Hz, filenum is included in file name, this is because each small file is normalized separately see example here https://jlabsvn.jlab.org/svnroot/solid/study/background/background.C and https://jlabsvn.jlab.org/svnroot/solid/study/trigger/Get_PVDIS_LD2_trigger_rate.C
