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. + Contents: .. toctree:: :maxdepth: 2 + install + geometry + render + simulation + likelihood + Indices and tables ================== |
