A compact dication source for Ba2+ tagging and heavy metal ion sensor development
Navarro, K.E.; Baeza-Rubio, J.; Boyd, M.; Foss, F.W.; Giri, S.; Jones, B.J.P.; Miller, R.L.; Nygren, D.R.; Samaniego, F.J.; Stogsdill, K.We present a tunable metal ion beam that delivers controllable ion currents in the picoamp range for testing of dry-phase ion sensors. Ion beams are formed by sequential atomic evaporation and single or multiple electron impact ionization, followed by acceleration into a sensing region. Controllability of the ionic charge state is achieved through tuning of electrode potentials that influence the retention time...
