Abstract

We constructed a new polarized He-3 ion source in order to establish a method of principle of "electron pumping" and experimentally prove its validity. Electron pumping utilizes multiple electron capture and stripping collisions of He-3(+) with rubidium atoms whose vapor thickness is much thicker than that used in an ordinary optical pumping polarized ion source. Special care was paid in the design of a rubidium vapor cell, a pumping laser and a beam transport system. We present details of the device and report the present status of the development.
