GCF Generator
Repository:
https://github.com/JacksonPybus/GCF_Generator_Suite/
This is currently a private repository. If you do not have access, contact Jackson Pybus (jrpybus@mit.edu) and request to be added as a collaborator
How to run:
Compile
Navigate to a build directory of your choice (i.e. GCF_Generator Suite/build)
ccmake [path to]/GCF_Generator/src
make
Run
Navigate to build/programs/genPhoto
./genPhoto [Z] [N] [Beam Energy] [outputFile.root] [# of prescribed events]
The output file will be a ROOT file with a tree of particle momentum, particle ID codes in PDG format, and event weights in units of nanobarns. Note that to determine the absolute cross section, it is necessary to divide by the prescribed number of events, rather than the written number of events.
Hall D software requires particle information to be provided in "HDDM" format to be used in propagation and reconstruction; such files can also be converted for ASCII-formatted files. To produce events written in this format, run the generator with the following options:
./genPhoto [Z] [N] [Beam Energy] [weights.root] [# of prescribed events] -A [outputFile.txt]
The ROOT file will have a tree containing only the event weights; the text file will be an ASCII-formatted file containing particle information. To convert this file to "HDDM" format, follow instruction given in the following section.

Repository:
- Reconstruction:

Geant Geometry
& Install software:
git clone https://github.com/jeffersonlab/halld_recon
How to run
Compile plugin
scons -u install
Location of data
List of runs:
https://halldweb.jlab.org/rcdb
on ifarms:
/cache/halld/RunPeriod-2019-01/rawdata/Run061914/hd_rawdata_061914_*.evio
Data on tape:
ls /mss/halld/RunPeriod-2019-01/rawdata/
Retrieve file from tape:
jcache get /mss/halld/RunPeriod-2019-01/rawdata/Run_number/*.evio
Examples:
Convert ASCII file to the hddm format (Gluex Simulation format)
genr8_2_hddm input_file.txt
will create an output file input_file.hddm
You can copy genr8_2_hddm.cc from the directory below to your libs and recompile
/work/halld2/home/somov/SRC/src_lib/halld_sim/src/programs/Simulation/genr8_2_hddm
(or use the program from /w/halld-scifs17exp/halld2/home/somov/SRC/src_lib/halld_sim/Linux_CentOS7.7-x86_64-gcc4.8.5/bin/genr8_2_hddm)
Process events through Geant
- Copy files setenv.csh and control.in from /work/halld2/home/somov/SRC/src_geant to your dir
- Update directories in 'setenv.csh'
- source setenv.csh
- Geant is handled using control.in file. Update parameters (name of INPUT/OUTPUT files, number of events you want to process) in this file.
- hdgeant
