Objective
The deuteron, the simplest two-body nuclear system, is a unique laboratory to study the dynamical effects in nuclei. Reactions with polarized targets offer much more detailed information on the system under study in terms of polarization observables, which are sensitive to small amplitudes and to small contributions of interesting dynamical effects. The project is aimed at the precise measurements of the polarization observables in the elastic electron scattering on polarized deuteron and quasielastic proton knock-out from the polarized deuteron. The experiment will be performed at the VEPP-3 2 GeV electron storage ring in Novosibirsk using a method of superthin internal target. The large acceptance non-magnetic particle detector should allow in a single run to take data on elastic scattering in a momentum transfer range 3-5 fm-1 and simultaneously in electrodisintegration channel in a wide range of the center-of-mass energy and scattering angle of the final proton-neutron pair. The project includes the development and commissioning of a new intense source of polarized deuterium atomic beam which should provide a flux of polarized deuterium atoms of 0.9*10**17 atoms/sec (in two states) directed to the cooled storage cell, resulting in a thickness of the polarized internal target of 0.9*10**14 atoms/cm2. The estimated tensor polarization of the target is Pzz = +0.8 or -1.6. The data to be collected in a 500-hour run with an averaged electron current of 100 mA will allow to measure the T20 component of the analyzing power in elastic electron-deuteron scattering with a statistical accuracy of 5-15 percent depending on the momentum transfer, the T21 component with an accuracy of 15-30 percent and the tensor asymmetry in the quasi-elastic proton knock-out with 5-10 percent accuracy.
