This code includes the following features:

• Radiation Reaction (RR)
  • Landau-Liftshitz (LL)
  • Sokolov (SKL)
  • Stochastic (SCS)
• Classical and QED-assisted model for LL & SKL
• Radiation model
  • Nonlinear Compton Scattering
• Simulating a single electron or an electron bunch
• Calculating radiation spectrum and photon number distribution
• Calculating radiation angular distribution
• Pair production
  • Bethe-Heitler
  • nonlinear Breit-Wheeler (to do)
• Laser field beyond paraxial approximation up to fifth order
• Spatial and temporal Gaussian shape laser pulse (Linear & Circular polarisation)
• Load electron beam energy distribution from experimental data

To begin, the following dependencies are required:

• fortran compiler (e.g. gfortran)
• Massage Passing Interface, MPI (e.g. OpenMPI)
• OpenMP

./LEC.cmp

echo Data | mpirun -np 32 ./bin/LEC

where Data is a folder contains the input.dat file. To set the number of threads export OMP_NUM_THREADS=n, where n is the number of thread. To run multiple simulations at one run, prepare DataN with each input and execute ./LEC_multirun.jcf. Please modify this file for N.
