Experimental ion mobility measurements in Xe-CO₂

Data on ion mobility is important to improve the performance of large volume gaseous detectors. In the present work the method, experimental setup and results for the ion mobility measurements in $Xe-CO_2$ mixtures are presented. The results for this mixture show the presence of only one peak for all gas ratios of Xe-CO(2), low reduced electric fields, E/N, 10-25 Td $(2.4-6.1 kV·cm^{−1} ·bar^{−1})$, low pressures 6-8 Torr (8-10.6 mbar), at room temperature.
