| Abstract: | Gas mixing technique has been used in order to increase the current of highly charged ions of Xe at the TIFR-ECRIA. The He, N2, O2, Ne, and Ar are used as support gases, and their effect on output currents of Xe ions is studied. The effective ion charge and the total loss rate of ions are calculated from the measured currents. It is found that molecular gases, such as N2 and O2, exhibit better mixing effect in the enhancement of output of highly charged Xe ions. Furthermore, we describe this 14.5-GHz ECR ion source mounted on a high voltage (400 kV) deck, with its four beamlines, as well as the control system for the remote operation. |
