GEANT4 Simulation Dataset for a CMS-Like PbWO4 Electromagnetic Calorimeter

This dataset contains simulated energy deposition data for a cylindrical electromagnetic calorimeter (ECAL) inspired by the geometry of the CMS detector. The simulations were performed using the particle transport toolkit GEANT4 version 11.2 and are intended for studies of electromagnetic shower reconstruction and machine learning applications in calorimetry. The detector consists of a cylindrical array of a single layer of lead tungstate crystals (PbWO₄) arranged in a barrel configuration with: crystal cross-section: 2.2 × 2.2 cm² crystal depth: 23 cm detector radius: 1.290 m 85 crystals in beam direction (corresponds to the 0 CreateNtupleDColumn("TotalEn"); // Total deposited energy analysisManager->CreateNtupleDColumn("InitialMomentum"); // Energy of the generated photon analysisManager->CreateNtupleDColumn("InitialColumn"); // Photon impact position (fractional ieta) analysisManager->CreateNtupleDColumn("InitialRow"); // Photon impact position (fractional iphi) analysisManager->CreateNtupleDColumn("EnergyVector", fEventAction->GetHadCalEdep()); // 1D array of energy deposited in (ieta, iphi) cells analysisManager->CreateNtupleDColumn("Row", fEventAction->GetHadCalRow()); // 1D array of iphi indices associated to the energy deposits analysisManager->CreateNtupleDColumn("Column", fEventAction->GetHadCalColumn()); // 1D array of ieta indices associated to the energy deposits analysisManager->CreateNtupleDColumn("z", fEventAction->GetHadCalPlane()); // Plane (z=0 for a single layer of PbWO4) For more information about the GEANT4 simulation implementation, please feel free to contact the authors.
