SBND and DUNE - state of the art liquid argon TPCs for neutrino physics

The field of neutrino physics is now moving towards the era of precision physics in order to test the 3-neutrino paradigm, neutrino mass hierarchy and CP asymmetry in the lepton sector.  The next generation of neutrino detectors, currently under development and construction, will have sensitivity to the fundamental parameters which describe these phenomena.

Liquid argon is an excellent detector medium, with good scintillation and charge transport properties. Coupled with the three dimensional position reconstruction possible with a time projection chamber, it makes for a powerful particle detector which has become one of the detectors of choice for rare event physics, especially in neutrino detection.  This rapidly developing field has many technical challenges as the desired detector volume increases to the multi-kiloton scale. 

I will discuss both the Short Baseline Neutrino (SBN) programme and Deep Underground Neutrino Experiment (DUNE) with a focus on the detector technology used for both, discussing the current status and future prospects for these accelerator neutrino experiments.
