Studying Effects of Temperature and Pressure on Measurements of the TPC Gas Monitoring Chambers for the T2K Near Detector Upgrade — Stefan Roth, Keitlin Sejdarasi, •David Smyczek, Jochen Steinmann, and Nick Thamm — RWTH Aachen University - Physics Institute III B, Aachen, Germany

A new pair of Time Projection Chambers for high angle measurements (HATs) are part of the T2K near detector upgrade. For their calibration, the gas parameters will be continuously monitored using newly developed Gas Monitoring Chambers (GMCs). Besides the gas mixture itself, temperature and pressure have a large effect on the monitored gas parameters. Only by measuring these environmental variables, and including them inside the analysis of the gas, significant statements about the gas parameters and quality can be made. Furthermore, the surrounding temperature influences the GMC setup, affecting the measurement process. The status of these investigations is presented.
