Neutrino oscillations intrinsically confirm that neutrinos have a non-zero mass, indicating that there is physics beyond the Standard Model of Particle Physics where these particles are massless.
To date, it is not yet known what the absolute values of the neutrino mass states are and how the neutrino masses are ordered.
Also, precise measurements of the extent of CP violation in the lepton sector have yet to be conducted.
These are the goals of the Deep Underground Neutrino Experiment (DUNE), an accelerator-based neutrino oscillation experiment currently under construction in the USA.
The experiment makes use of Liquid Argon Time Projection Chambers (LArTPCs) in the near- and the far-detectors.
Close to the neutrino production site, the very high neutrino flux poses challenges for the near-detector that has to deal with event pile-up.
To address these problems, the ArgonCube collaboration has developed a modular LArTPC design and new technology for better sensitivity and event reconstruction capabilities.
The three main ArgonCube technologies are:
A pixelated charge readout for amplification and digitization in LAr,
a SiPM-based light readout system to detect the LAr scintillation light,
and a new technology using a thin foil with a high electrical resistivity to shape the TPC drift fields.
ArgonCube will find application in the DUNE near-detector and was also proposed for one of the four far-detector modules.
In this talk, I'm going to present the ArgonCube concepts and technologies, and the path toward the DUNE near-detector.
