Run GEMC Isotropic Theta and Phi for Sector 1 DC
LUND Splitting
Using CLAS12 isotropic distribution LUND files for LH2 and NH3 targets and varying incident electron energy we are limited in the number of particles GEMC can work with. Since theta has a range of 35 degrees, by .1 degree increments, this gives 350 different particles as a function of theta. Similarly, for phi with a range of 60 degrees, by .2 degree increments, we find 300 different phi values. Combing these results we should have 105000 unique theta-phi combinations. Since LUND files have 3 lines for every 1 particle simulated we should have 315000 lines in an Theta and Phi Isotropic distribution LUND file. Using the result of the LUND file created earlier:
~/src/CLAS/GEMC/experiments/eg12/MolrBckGrd/DV/Isotropic_study/LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut> wc -l LUND_Spread_LH2_IsotropicPhi.LUND 315000 LUND_Spread_LH2_IsotropicPhi.LUND
Moving the LUND file into a directory style name
mv LUND_Spread_LH2.LUND LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut.LUND
Spliting the LUND file into 105 parts of 1000 events, or 3000 lines
split -d -l 3000 -a 3 LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut.LUND LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut_
Naming these files LUND files
prename 's/(LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut_\d{3})/$1.LUND/' LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut_*
Placing each of these files into its own directory, within a directory named LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut
find . -name "*.LUND" -exec sh -c 'mkdir "${1%.*}" ; mv "$1" "${1%.*}" ' _ {} \;
GCard Building
A program,File:Gcard builder.C is written to install a LUND specific gcard in each directory.
Commands Building
Similarly, File:Commands builder.C is written to install a specific commands file into each directory for testing.
Batch Conditions for GEMC 2.4
The batch job will need to
cd /home/lds/src/CLAS/GEMC/experiments/eg12/MolrBckGrd/DV/Isotropic_study/LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut
cd /LH2_0Sol_n100Tor_11GeV_Phi10deg_ShieldOut_00
~/src/CLAS/GEMC/source/gemc -USE_GUI=0 -INPUT_GEN_FILE="LUND,LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut_000.LUND" -N=3000 eg12.gcard>/dev/null

The weighting found in the LUND file is applied to the scattering angle theta in the Center of Mass frame to produce the Moller Differential Cross Section. We should be able to use the information from the detector hits such as wire numbers and sectors to find a distribution of hits with respect to the scattering angle theta in the Lab Frame. The Theta distribution will need to undergo a Lorentz transformation to the Center of Mass Frame to apply the corresponding weight found in the LUND file. To do this, a qsub batch command can be created:
File:Submit builder.C
These files are run by creating another file
Running this
source minervesubmit_LH2_0Sol_0Tor_11GeV_IsotropicPhi_ShieldOut
Batch Conditions for GEMC 3.0
To run a "batch job" we will use screen and bash scripts as follows
screen -S 1 cd ~/src/CLAS/GEMC tcsh source setup
Where setup has
setenv JLAB_ROOT /home/lds/src/CLAS/GEMC setenv JLAB_VERSION 2.1 #setenv JLAB_VERSION 1.3 #setenv JLAB_VERSION 4.0 source $JLAB_ROOT/$JLAB_VERSION/ce/jlab.csh setenv CLARA_HOME /home/lds/src/CLAS/CLARA/myCLARA
We can create a submit file generator
We can also create a Batch file generator
This is run by
./Pre-submit ./Block001
