Research and development on optically pumped polarized-ion sources. Technical progress report, February 1, 1983-January 31, 1984

Technical Report ·
OSTI ID:5737431
During the past year we have carried out research on the formation of optically pumped polarized Li/sup -/ or Na/sup -/ ions. The basic idea for an optically pumped Li/sup -/ or Na/sup -/ ion source was proposed independently by Fick and by Anderson and Nimmo. A beam of Li or Na atoms is produced by an atomic beam oven. The Li or Na atoms are polarized by optical pumping. The polarized Li or Na atoms are incident on a heated oxidized tungsten surface where they are surface ionized to form polarized Li/sup +/ or Na/sup +/ ions. The polarized Li/sup +/ or Na/sup +/ ions are extracted, accelerated, focussed, and partially converted to polarized Li/sup -/ or Na/sup -/ in a K or Cs vapor cell. It is known that if the nuclei of the Li or Na atoms are polarized when the atoms hit the oxidized tungsten surface ionizer and if the ionizer is hot enough then the Li/sup +/ or Na/sup +/ ions formed are polarized. A primary question in making an optically pumped polarized Li/sup -/ and Na/sup -/ ion source is, What is the best method of optical pumping for the Li or Na atom beam. During the past year we have carried out a number of experiments necessary to answer this question. This Progress Report describes briefly the experiments we have carried out and summarizes the results of these experiments.
