SoLID full simulation and file sharing
Contents
Introduction
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
Luminosity and radiation thickness
file sharing
The file size is large in order of 50GB, you can transfer them by using "scp jlabname@ftp.jlab.org:file" slowly or other faster ways like globus here https://cc.jlab.org/filetransfers

- 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

main report for PVDIS_LD2 pptxpdf and SIDIS_He3 pptx pdf
The code are in SVN at https://jlabsvn.jlab.org/svnroot/solid/solid_gemc/analysistool/background see log files there for details
EM background is estimated from shooting beam into target with SoLID GEMC
background from eDIS, eES and hadron are using event generator at vertex as input into SoLID GEMC
low energy neutron cross section was turned on
file location for SIDIS_He3 /work/halla/solid/sim/solid_gemc/SIDIS_He3_run1
file names for SIDIS_He3 file with no special name is just shooting beam on target, "EM" particles dominating the results "other" in file name means kryptonite for all geometry "actual" in file name mean all real materials "sum" in file name mean sum over all real materials for gas and two windows
file location for PVDIS_LD2 /work/halla/solid/sim/solid_gemc/PVDIS_LD2_run1 main result is dir baffle_babarbafflemore1_block which has photon block before EC while baffle_babarbafflemore1 has result without the photon block
file names for PVDIS_LD2 file with no special name is just shooting beam on target, "EM" particles dominating the results "other" in file name means kryptonite for all geometry "real" in file name mean lead baffle and kryptonite for everything else
for different detector and for different particles, we have histograms showing rate "Eklog_R_hitid_pid" rate(kHz/mm2) at R(cm) and log10(Ek)(GeV) with bin(300, 0, 300, 200,-6,1.3) "Eklog_R_high_hitid_pid" rate(kHz/mm2) at R(cm) and log10(Ek)(GeV) with bin(300, 0, 300, 200,-6,1.3) for Phi (0,6)deg "Eklog_R_low_hitid_pid" rate(kHz/mm2) at R(cm) and log10(Ek)(GeV) with bin(300, 0, 300, 200,-6,1.3) for Phi (6,12)deg "Eklog_R_Phi_hitid_pid" rate(kHz) at Phi(deg), R(cm) and log10(Ek)(GeV) with bin(48,0,12,300, 0, 300, 200,-6,1.3) "P_R_hitid_pid" rate(kHz/mm2) at R(cm) and P(GeV) with bin(300, 0, 300, 1100,0,11) there are many other histograms produced with similar names
Because all histograms are produced the same way. One can simply add root files together by "hadd" to look at the result in sum
