High Granularity Electromagnetic Shower Images

This is a limited subset of the data used for training in <strong>arXiv:2005.05334</strong>. The network architectures and instructions to generate more data are available at here. Electromagnetic calorimeter for the ILD consists of 30 active silicon layers in a tungsten absorber stack with 20 layers of 2.1 mm followed by 10 layers of 4.2 mm thickness respectively. We project the sensors onto a rectangular grid of 30×30×30 cells. Each cell in this grid corresponds to exactly one sensor, resulting in total of 27k channels. The file has the following structure: Group named <em>30x30</em> <em>energy</em> : Dataset {1000, 1} <em> layers</em> : Dataset {1000, 30, 30, 30} The <em>energy</em> specifies the true energy of the incoming photons in units of GeV, where <em>layers</em> represent the energy deposited (MeV) in 30 layers of the calorimeter in an image data format. This file contains approximately 24.000 showers.
