Abstract

A new atomic beam type polarized alkali ion source has been installed at the MP tandem accelerator in Heidelberg. By thermal evaporation and collimation Li and Na atomic beams are formed. Polarization is produced by optical pumping and a 4-pole Stern-Gerlach magnet which results in beams in a single Zeeman m-state. The population is shifted to any m-state by an adiabatic high frequency transition in a medium field (MFT). The purity of m-state population has been measured to be between 0.95 and 0.98, which results in nuclear polarization P > 0.9, s=z,zz. At the surface ionizer of the ion source beams of 15 to 65 μA of positive ions have been extracted of optically pumped Li and Na ions, respectively.
