Computing infrastructure at the CERN neutrino platform prototypes experiments

Abstract

Abstract The Neutrino Platform (NP) is the CERN venture to foster and support the next generation of accelerator-based neutrino oscillation experiments. Part of the present CERN Medium-Term Plan, the NP provides facilities to develop and prototype the next generation of neutrino detectors while contributing to unify the European neutrino community towards the US and Japanese projects. A significative effort is made on R&D for LAr TPC technologies: two big LAr TPC prototypes for the DUNE far detector are under construction at CERN. Those detectors will be exposed in summer 2018 to an entirely new and NP-dedicated beam-line from the SPS which will provide electron, muon and hadron beams with energies in the range of sub-GeV to a few GeV. The total raw data volume that is slated to be collected during the scheduled 3-month beam run is estimated to be in excess of 2.5 PB for each detector. In this paper, the current status of NP Computing Infrastructure approach is presented to solving these problems by leveraging the design, expertise and components into a unified architecture that is capable of meeting the needs of NP prototypes experiments.
