Description
Antihydrogen (¯H) atoms are produced via laser-controlled, two-stage charge exchange in a cryogenic Penning trap. 6x10^6 antiprotons (¯p) and 3x10^8 positrons (e+) are held in a nested well potential structure. Cs* atoms, produced via laser excitation within the cryogenic Penning trap, travel radially across the trap and through the e+ plasma to produce Ps*. The Ps* atoms are produced isotropically, with some atoms moving along the axis of the Penning trap and interacting with the cold ¯p via a second charge exchange to form potentially very cold ¯H. ¯H formation is detected by comparing the ¯p annihilation counts with Cs excited to the Rydberg state to those obtained when the Cs remains in the ground state.
