Monte Carlo generator of high energy electron-proton and electron-nucleus bremsstrahlung events
The structure of the generator is described in a pdf file: bremge_short_description.pdf . It was written as a FORTRAN 77 package.
After downloading the directory the compilation is needed: gfortran bremge.F brebldt.F -o main main.F
In order to run the generator inside eic-environment just execute: ./main
- brebldt.F - the cuts are set
- main.F - number of events are set
- fort.7 - is the output of the generation:
- eg0, ee: photon and electron energy
- tgx, tgy: photon scattering angles
- tex, tey: electron scattering angles
hepMC3: Bremge generates the scattering angles of the electron and photon with respect to the positive direction of the z-axis.
In the program: bremge_to_hepmc3.cxx they are reversed to be compatible with EIC geometry simulation programs.
Validation
- is performed by comparison of the resulting particle distributions with GETaLM beam effects simulation.
- theta angle for photons from Bremge and GETaLM
phi angle for photons from Bremge and GETaLM
phi angle for electrons from Bremge and GETaLM
energy for photons from Bremge and GETaLM
energy for electrons from Bremge and GETaLM
