Chroma: Ultra-fast Photon Monte Carlo ===================================== Chroma is a high performance optical photon simulation for particle physics detectors. It tracks individual photons passing through a triangle-mesh detector geometry, simulating standard physics processes like diffuse and specular reflections, refraction, Rayleigh scattering and absorption. With the assistance of a CUDA-enabled GPU, Chroma can propagate 2.5 million photons per second in a detector with 29,000 photomultiplier tubes. This is 200x faster than the same simulation with GEANT4. Development ----------- Chroma is under heavy development. Tagged releases will happen soon, but in the meantime we encourage people to obtain the code directly from the Mercurial repository hosted at Bitbucket: http://bitbucket.org/chroma/chroma For questions, ideas, and discussion, join the Chroma development mailing list: http://groups.google.com/group/chroma-sim For bug reports, please create a Bitbucket account and use the Bitbucket issue tracker: https://bitbucket.org/chroma/chroma/issues?status=new&status=open Documentation ------------- The core concepts are described in the :download:`Chroma whitepaper `. The software documentation is evolving rapidly, so many of the following sections are incomplete at the moment.
