First measurements with a gas monitoring chamber at subatmospheric pressures — Rebecca Fischer, Thomas Radermacher, Stefan Roth, David Smyczek, and •Nick Thamm — RWTH Aachen University - Physics Institute III B, Aachen, Germany

Time projection chambers (TPCs) are gaseous ionization detectors, which can instrument large volumes for particle tracking applications. By adjusting the internal gas-mixture and the operating pressure it is possible to fine-tune these detectors to have increased target mass for neutrino interactions or improved track resolution for low energies. For the precise operation of TPCs various electron swarm parameters are usually measured during runtime with a gas monitoring chamber (GMC), a small specialized TPC. These monitoring chambers can also be used for the verification of drift parameter simulations, which help predict the physics behavior of larger detectors. In this talk the hardware modification of a high pressure GMC (HPGMC) towards low pressure operation is addressed, the associated challenges are explained and first measurement results are shown.
