Spin flips of a single proton were driven in a Penning trap with a homogeneous magnetic field.
For the spin-state analysis the proton was transported into a second Penning trap with
a superimposed magnetic bottle, and the continuous Stern–Gerlach effect was applied.
This first demonstration of the double Penning trap technique with a single proton suggests
that the antiproton magnetic moment measurement can potentially be improved by three
orders of magnitude or more.
