摘要：

We have utilized the spin-dependence of the cross section for electron impact ionization of H0 and D0 atoms in the ionizer of our atomic beam polarized ion source to study the performance of the rf transitions which provide the nuclear polarization of the atomic beam. Switching the rf transitions on and off modulates the output polarized beam current. This modulation is observed using a lock-in amplifier and provides a fast and reliable method for optimization of transition unit parameters.
