CaloFlux: a tool to estimate fluxes in calorimeters at colliders

In high-granularity calorimetry, as proposed for detectors at future electron-positron Higgs factories, the requirements on electronics can have a strong impact on the design of the detector, especially via the cooling and data acquisition systems. Estimating the data rate is a difficult task due to the very large number of channels, the complexity of the calorimeter system's geometry, and the intricacies of the readout system. The CaloFlux software package presented here eases this task by establishing the typical fluxes-deposited energy, number of cells above the electronics threshold, power consumption, and associated data-in rate histograms for selections of components, from fully simulated physics and background events by scaling with proper rates. The ILD calorimeter system is taken as a specific example, upon which different histograms are obtained for representative parts of the calorimeter and for various machine configurations. Examples of histograms are shown, along with details of the data used and the simulation.
