Antiprotons (p̄) remain confined in a Penning trap, in sufficient numbers to form antihydrogen (H̄) atoms via charge exchange, when the radial field of a quadrupole Ioffe trap is added. This first demonstration with p̄ suggests that quadrupole Ioffe traps can be superimposed upon p̄ and e+ traps to attempt the capture of H̄ atoms as they form, contrary to conclusions of previous analyses.
