Gas Monitoring Chambers for the T2K Near Detector Upgrade — Ines Hannen, Thomas Radermacher, Stefan Roth, •David Smyczek, and Nick Thamm — RWTH Aachen University - Physics Institute III B, Aachen, Germany

A new pair of Time Projection Chambers for high angle measurements (HATs) will be installed during the upgrade of the T2K near detector ND280. For their calibration the gas parameters will be continuously monitored using newly developed Gas Monitoring Chambers (GMCs). Systematic measurements of drift velocity and gas gain have been performed for different gas mixtures. These measurements are compared to simulations and previous measurements. The test setup and measurement results are presented.
