Abstract: (IOP)
We present a tunable metal ion beam that deliverscontrollable ion currents in the picoamp range for testing ofdry-phase ion sensors. Ion beams are formed by sequential atomicevaporation and single or multiple electron impact ionization,followed by acceleration into a sensing region. Controllability ofthe ionic charge state is achieved through tuning of electrodepotentials that influence the retention time in the ionizationregion. Barium, lead, and cadmium samples have been used to test thesystem, with ion currents identified and quantified using aquadrupole mass analyzer. Realization of a clean Ba ion beam within a bench-top system represents an important technicaladvance toward the development and characterization of bariumtagging systems for neutrinoless double beta decay searches in xenongas. This system also provides a testbed for investigation of novelion sensing methodologies for environmental assay applications, withdication beams of Pb and Cd also demonstrated for thispurpose.- Beam Optics
