Description
The Deep Underground Neutrino Experiment (DUNE) plans to collect physics
data for over 10 years, starting in 2029. The full DUNE design consists of four far
detectors with multiple 10 kT fiducial mass LArTPCs and a heterogeneous near
detector complex with 1300 km between them. This combination of technologies
and readout time scales is expected to require large storage volumes with on the
order of several GBs stored per readout window in the far detector alone. DUNE
currently relies on ROOT for a columnar binary data storage format, geometry
modelling, fitting algorithms, and more. Before the start of data taking, DUNE
is replacing its art framework with the new Phlex framework, with RNTuple
support through the FORM I/O toolkit. Additionally, DUNE analysis tools
continue to integrate more use of scientific python where possible. Therefore,
the development of ROOT 7 is particularly timely for DUNE. This presentation
will survey how ROOT performs in DUNE’s current software stack and where
the future of ROOT can have a meaningful impact on this experiment.
