Tests of a Polarized Source of Hydrogen and Deuterium Based on Spin-Exchange Optical Pumping and a Storage Cell for Polarized Deuterium.

摘要

A novel laser-driven polarized source of hydrogen and deuterium which is based on the principle of spin-exchange optical pumping has been developed at Argonne. The advantages of this method over conventional polarized sources for internal target experiments is discussed. At present, the laser-driven polarized source delivers hydrogen 8 x 10 sup 16 atoms/s with a polarization of 24% and deuterium at 6 x 10 sup 16 atoms/s with a polarization of 25%. A passive storage cell for polarized deuterium was tested in the VEPP-3 electron storage ring. The storage cell was found to increase the target thickness by approximately a factor of three and no loss in polarization was observed. 10 refs., 4 figs., 2 tabs. (ERA citation 14:013389)
