Mass Selective Acceleration at the Test Storage Ring — •Felix Laux1, Robin Bastert1, Henrik Buhr2, Manfred Grieser1, Claude Krantz1, Mario Mendes1, Andreas Wolf1, and Klaus Blaum11Max-Planck-Institut für Kernphysik, Heidelberg — 2Weizmann Institute of Science, Rehovot, Israel

The Test Storage Ring (TSR) at the Max-Planck-Institut für Kernphysik in Heidelberg has recently been successfully used for mass selective acceleration. This newly developed method renders the possibility of effective separation of ion species with small relative mass differences. We report on an experiment in which we were able to separate the desired DCND+ from nearly isobaric N2D+ and DCO+ with mass selective acceleration, although the relative mass differences of the two neighbouring species are as small as Δ m/m ∼ 4·10−4. The composition of the accelerated beam was analyzed by collisional fragmentation measurements.
