Development of a High Pressure Time Projection Chamber — •Philip Hamacher-Baumann, Thomas Radermacher, Stefan Roth, and Nick Thamm — III. Physikalisches Institut B, RWTH Aachen University

Gaseous detectors have long been used by particle physics experiments. Their low momentum threshold has made them interesting as active targets for long baseline neutrino experiments. To increase the statistics of neutrino interactions, but retain a low momentum threshold, pressurized Time Projection Chambers (TPCs) have been proposed. The Deep Underground Neutrino Experiment (DUNE) considers building one as part of its near detector complex.

Gas Monitoring Chambers are mini TPCs that are designed to measure gas properties. Such a system with the capability of testing common and new drift gas mixtures can provide input to the design process of new high pressure TPCs. This talk presents a High Pressure Gas Monitoring Chamber (HPGMC), capable of operating up to 10 bar pressure and a maximum drift field close to 1000 V/cm.
