CaloHadronic

The International Large Detector (ILD) is a detector concept proposed for future electron positron Higgs factories, originally designed for operation at the International Linear Collider (ILC). The ILC is a proposed linear electron-positron collider that will initially operate at a center-of-mass energy of 250 GeV with the option to upgrade it to 1 TeV, with a rich program of Higgs-, Electroweak- and BSM physics. ECAL Electromagnetic showers are measured with a compact highly-granular calorimeter with absorber plates made of tungsten. The ECAL barrel shape is octagonal with individual stacks laid such as to avoid projective dead zones in azimuth. The number of layers is 30. The sensitive mediumconsists of silicon sensors with about 5x5 mm^2 readout cells.HCAL The hadronic calorimeter consists of 48 longitudinal samples with steel absorber plates. The HCAL layers are instrumented with high granularity for an efficient separation of charged and neutral hadronic showers, necessary for particle flow, as well as for a good muon identification for flavor jet tagging. ROOT file: All Geant4 steps were extracted from the sensitive layers of both calorimeters, yielding a total of 78 layers of 2D point clouds. HDF5 file: each layer is projected onto virtual grid with different granularities for ECAL and HCAL. The granularity of the grid was chosen to reflect the resolutions of the calorimeter subsystems: a finer 1.7x1.7 mm^2 granularity was used for the ECAL, while a coarser 10x10 mm^2 granularity was used for the HCAL. All layers were stacked along the y-axis, with the y-coordinate assigned according to the layer number. A random offset uniformly sampled from the interval ±0.5 was applied to each point’s y-position, dequantizing the longitudinal shower profile.
