We report the successful trapping of $6\ifmmode\times\else\texttimes\fi{}{10}^{6}$ ${}^{82}\mathrm{Rb}$ ${(t}_{1/2}=75\mathrm{s})$ atoms with a trap lifetime of $\ensuremath{\sim}30\mathrm{s}$ in a magneto-optical trap that is coupled to an off-line mass separator. Efficient sample introduction is achieved by implanting ${}^{82}\mathrm{Rb}$ ions into a small yttrium catcher foil located inside the trapping cell. Upon heating, the radioactive atoms are released from the foil and trapped without significant gas loading. This advancement makes a variety of high-precision electroweak interaction experiments possible, including the measurement of \ensuremath{\beta}-decay correlations associated with spin-polarized ${}^{82}\mathrm{Rb}$ nuclei.We report the successful trapping of $6\ifmmode\times\else\texttimes\fi{}{10}^{6}$ ${}^{82}\mathrm{Rb}$ ${(t}_{1/2}=75\mathrm{s})$ atoms with a trap lifetime of $\ensuremath{\sim}30\mathrm{s}$ in a magneto-optical trap that is coupled to an off-line mass separator.

Two-symmetry Penning-Ioffe trap for antihydrogen cooling and spectroscopy

E. R. Tardiff, Xing Fan, G. Gabrielse +12 more

High-accuracy spectroscopic comparisons of trapped antihydrogen atoms (H¯) and hydrogen atoms (H) promise to stringently test the fundamental CPT symmetry invariance of the standard model of particle physics. ATRAP’s nested Penning-Ioffe trap was developed for such studies. The first of its unique features is that its magnetic Ioffe trap for H¯atoms can be switched between quadrupole and octupole symmetries. The second is that it allows laser and microwave access perpendicular to the central axis of the traps.High-accuracy spectroscopic comparisons of trapped antihydrogen atoms (H¯) and hydrogen atoms (H) promise to stringently test the fundamental CPT symmetry invariance of the standard model of particle physics.
