Slow antihydrogen (H̄) is produced within a Penning trap that is located within a quadrupole Ioffe trap, the latter intended to ultimately confine extremely cold, ground-state H̄ atoms. Observed H̄ 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 H̄ atoms actually increases when a 400 mK Ioffe trap is turned on.
