“…In this work, the mobility of ions in Ar-N 2 gas mixtures was measured at a pressure of 8 Torr (10.6 mbar) and for reduced electric fields commonly used in gaseous detectors, 15 Td (3.6 kV•cm −1 •bar −1 ), extending previous studies developed in our group for other gases [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”

“…The Monte Carlo simulation code used is described in detail in [31], and as in [21], a uniform field was considered inside the GEM holes, between anode and cathode. Although this is an approximation of the real field geometry, it has already provided valuable information for this purpose in previous studies.…”

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.
