Experimental ion mobility measurements in Xe-CO₂

Abstract

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.

Experimental ion mobility measurements in Ar-N2

“…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 mobilities calculated did not display a significant dependence with E/N for the values used in this work (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25).…”

Experimental ion mobility measurements in Xe-CF4 mixtures

“…So, in the present work we studied the mobility of ions in xenon-carbon tetrafluoride (Xe-CF 4 ) gas mixtures in the 6 to 8 Torr (8 to 10.6 mbar) range and for reduced electric fields commonly used in gaseous detectors, extending previous studies developed in our group for other gases [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”
