Abstract
Abstract Description of the polarized deuterium gas target used at the VEPP-3 electron storage ring for experiments on elastic and inelastic ed scattering is given. Superconducting sextupole magnets with the pole tip magnetic field up to 4.8 T are used in atomic beam source (ABS) to focus atoms. The flux of polarized atoms injected into the storage cell was measured to be 8.2×10 16 at / s for deuterium and 7.9×10 16 at / s for hydrogen. The measured target thickness 8×10 13 at / cm 2 is consistent with the thickness calculated from the measured beam intensity. The effective tensor polarization of the deuterium target during the experiment was found to be P zz =0.397. Further improvements of the target and possible limitation of the beam intensity from ABS are discussed.
