Abstract: Slow antihydrogen ((H) over bar) is produced within a Penning trap that is located within a quadrupole Ioffe trap, the latter intended to ultimately confine extremely cold, ground-state (H) over bar atoms. Observed (H) over bar atoms in this configuration resolve a debate about whether positrons and antiprotons can be brought together to form atoms within the divergent magnetic fields of a quadrupole Ioffe trap. The number of detected (H) over bar atoms actually increases when a 400 mK Ioffe trap is turned on.
