Particle Detector Simulator

Interactive 3D collider-detector simulator: fire a collision event at the center and watch electrons, photons, hadrons and muons interact with the tracker, ECAL, HCAL and muon-chamber layers, then read off the particle-ID signature reconstructed from the hit pattern.

Fire a collision at the center of a layered barrel detector — tracker, electromagnetic calorimeter, hadronic calorimeter and muon chambers — and watch how electrons, photons, hadrons and muons each leave a distinct signature across the layers, the same way real collider detectors reconstruct particle identity and energy.
