Description
The DUNE near detector will consist of several components, one of which is the high-pressure gaseous argon time projection chamber, HPgTPC. As a fined-grained tracker with a low density and low detection threshold, it is well-suited to measure one of the most crucial sources of systematic uncertainty for neutrino oscillation measurements: nuclear effects in argon at the neutrino interaction vertex. In this talk, an overview of the HPgTPC design and its expected physics performance will be presented.
