Use of a storage cell in an experiment of 26 eV electron scattering on polarized deuterium atoms

Polarized deuterium atoms from a source directed into a storage cell are used as an internal target in the VEPP-3 electron storage ring. Jet source, conditions and results of the experiment on elastic and inelastic ed-scattering at 2 GeV electron energy are briefly described. The results of the experiment and calculations of atom depolarization in the jet by electron beam circulating in the storage ring are presented. As the experiment results show, atom depolarization in a cell due to collisions with walls is small, however depolarization of atoms by a high-frequency field of the 26 eV electron beam circulating in a storage ring can be significant. A variant of the suppression of electron beam depolarization effect is considered. 16 refs.; 13 figs
