Description

Presenting a generative model for detector simulation, that utilities normalising flows for macro-information, and iid diffusion models for fast details.

This is the third iteration of the CaloClouds series, which surpasses previous limits in inference speed. New, upgraded, capacities allow simulation of photons throughout the barrel of the detector. By integrating the model into the key4hep workflow we are able to produce realistic use-case results.
