Abstract
Data on ion mobility is important to improve the performance of large volume gaseous detectors, since the detector signal can be influenced by the drift of the ions, namely in the cases where charge multiplication is used, for example in Multi-Wire Proportional Chambers (MWPCs) and in some Time Projection Chambers (TPCs). In the present work the results for the ion mobility measurements in Ar-N-2 mixtures are presented, using an experimental setup and method already tested in previous work. The results for this mixture show the presence of only one peak for all gas ratios of Ar-N-2, for reduced electric fields, E/N, in the range of 10-25 Td (2.4-6.1 kV.cm(-1).bar(-1)), and 8 Torr (10.6 mbar) pressure, at room temperature.
