Ja. Behr et al., A LOW-ENERGY ION-BEAM FROM ALKALI HEAVY-ION REACTION-PRODUCTS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 351(2-3), 1994, pp. 256-260
We have tested and developed an ion beam apparatus for transporting al
kali atoms made in heavy-ion reactions. Stopped recoils diffuse out of
a hot thick target, are surface ionized, and extracted into a low-ene
rgy ion beam with efficiencies of approximately 20%. The ions are then
neutralized for injection into a magneto-optic trap.
