Description
A high flux, low energy ion beam facility has been designed, developed and commissioned at the Inter University Accelerator Centre (IUAC), New Delhi. [1, 2]. It mainly consists of a 2.45 GHz microwave ion source, a compact multi-electrode extraction system and an experimental chamber for performing experiments using intense ion beams in the energy range of a few keV to a few tens of keV. Various kinds of experiments have been carried out related to studies in materials sciences and plasma physics. The facility is planned to be upgraded using a compact Wien filter with a mass resolving power (m/m) of ~ 200, assuming slits are positioned at a distance of 100 mm from the exit of the filter. The Wien filter will transmit ions with velocities ranging from 0.97 x 10$^5$ m/sec to 13.83 x 10$^5$ m/sec. The results of beam optics simulations, the detailed design of the Wien filter and beam transport system will be presented.
