Workshop on simulation and data analysis

23 January 2019 – An internal KM3NeT workshop on ‘Simulation and Data Analysis’ was organised at INFN – Istitutio Nazionale di Fisica Nucleare in Genova, Italy. In the last two years the ARCA and ORCA sites were equipped with the first detection units which allowed for obtaining the first calibration data. The data comprises many measurements of muons created in the atmosphere. These measurements, although background to the neutrino signal, are extremely useful for the understanding of the detector performance and improving detector calibration and simulations of the detector response. The aim of the workshop was to review the currently existing simulation software tools and tuning them to reach agreement with the collected data on a new precision level.

Simulation of background events comprises very computationally intensive tasks, which must be run on the GRID and cloud infrastructures. For this, automatic workflows for the software deployment and running on different computer infrastructures were discussed and tests have been started. The simulation workflows also should keep provenance of the data to allow for repetition  and tracing of each simulated event. Automisation of the quality control of the data and simulation is yet another key task addressed at the workshop.
