CHIMERA: a code for FEL and laser plasma simulations

Build Status master Build Status dev CRAN

by Igor A Andriyash ([email protected])

CHIMERA is a relativistic electromagnetic particle-in-cell code, based on a quasi-cylindric pseudo-spectral analytical time domain (PSATD) Maxwell solver. More details on this method can be found in the original publications [1,2,3].


The code was tested only under Linux and MacOS. The recommended installation is through the Anaconda distribution. If Anaconda is not your default Python installation, download and install it from here.

  • install the dependances:
conda install gcc scipy h5py
conda install -c conda-forge fftw
  • clone the code source and cd into the folder (e.g. into ~/src/)
git clone
cd chimera
  • compile the Fortran 90 subroutines and install the code:
make install
  • code may be uninstalled using:
make uninstall
make clean
  • optionally, to enable export of synchrotron radiation data to VTK format install Mayavi (for tvtk api):
conda install vtk
pip install mayavi


  • you may need to adapt Makefile for your installation of Anaconda and FFTW.
  • you may need to heck the correct address to FFTW3 /lib/ and /bin/


To run CHIMERA in multiprocessor mode specify the OMP_NUM_THREADS variable.

For more information see demos in ./doc/
