Hydrogen-rich Gases for High Pressure Time Projection Chambers at Neutrino Beamlines — •Philip Hamacher-Baumann, Thomas Radermacher, Stefan Roth, and Nick Thamm — Physics Institute III B, Aachen, Germany

DUNE's near detector complex foresees a magnetized high-pressure gaseous time projection chamber (HPgTPC) as part of its detector suite. The gaseous active volume boasts a very low detection threshold with high particle-identification power and large acceptance for tracking. Especially interactions on the gas itself in the high intensity neutrino beam will be collected with an unmatched rate. For design and development of a pressurized TPC, it is essential to quantify and validate electron drift parameters, to predict performance of the final detector, e.g. HPgTPC. This presentation investigates how electron drift parameters of drift gas mixtures perform at higher than atmospheric pressures. Additionally, a study of hydrogen-rich Argon:Methane gas mixtures for consideration in HPgTPC is presented using measurements from a test chamber.
